  2. Physics relates to what interests me because it has to do with basketball. This video will tell you about the gravitational forces that have to do with a dunk, the act of forces, and defining momentum. These three examples all have to do with physics.

  3. Physics of softball and bat
    In this video it will show that the vibrational and acoustic analysis of softball and baseball bats correlate the vibrational frequencies to measured performance. There is a trampoline effect from the ball to the bat. That means that the ball bounces of the bat but its speed could vary.

  4. One of my favorite hobbies is softball, and in this website it talks bout projectile motion of three different softball pitches, fastball, rise ball, an change up. the website explains how when you pitch, no matter how level it looks it will always have an arc. The faster the ball goes the less of an arc it will have. Wind also plays a key role in the arc of the ball. If the wind is going towards home base then the ball will travel faster and will have less of an arc. If the wind is going against the pitcher the ball will take longer to get to the plate.
    Here is the link to the website: http://www.pitchsoftball.com/AllPitchesHaveanArc.html

    The sport that i do and love is football. I wanted to see how physics involves football and I found two videos. The first one shows Mass X Acceleration= Force.
    http://www.youtube.com/watch?v=5YdTLt_BbOs&feature=related
    The second video show forces, Gravity, Momentum, Collisions, Acceleration, Symmetry, and Newtons 1st law. Enjoy

  7. The vibration of cymbals interests me. The five or six modes the cymbal has are thought to cause the bending waves around the cymbal.
    also the Modal Frequencies of cymbals can be described by using a modified form of Chladni's law
    f=c(m+2n)p

    Physics and Soccer

    The movement of the soccer ball through the air is affected by the initial forces applied to it by the head or the foot, then while it is in the air, gravity and aerodynamic forces can cause to to curve. In this fallowing video it will show you those forces and it will also show the how it uses the Newtons 1st Law.

  9. Dancing with Physics

    Teaching physics by the way of the forces on the human body experience during dance. This video shows balance and finding your center of gravity. It shows how the girl tries to keep her balance on her toes without falling down and how she found her center of gravity.

  10. Running, like every movement, it involves a pendulum, velocity and mass. The way you move your body for example, the more you swing your arms and bend your knees, the faster you will run.A law of physics that comes into play holds that the amount of energy that you expend is directly proportional to movement. They say the less you bounce while you run and the more you lean forward the more efficient you will run. Another law: For every action there is an equal or opposite reaction. In this case, consider lifting your legs up rather than pushing away with your quads when running. It is much easier to lift your legs and push off with each step. As a result, you will minimize the reaction, or the energy required, by your body to move forward. Your stride will smooth out and you'll also minimize impact on your knees.

  12. I chose Wrestling as my interest. Newton's Third law ties in with wrestling, for example in wrestling the wrestlers are always in motion they push into one another. The force of one wrestler pushing into the other is equal to the force that the other is applying onto one. another example of force is the mat,the mats force is pushing up on the wrestlers. That is the same as the force of gravity therefore it keeps there feet stuck on the mat.

  13. My interest involve the study of animals like dogs to help me prepare to become a veterinarian. Every pet owner starts with basic training like "sit" for their pets. I found how training a dog to "sit" involves
    Theory of Relativity: "Sit" always means sit, but "No" is applied to an endless variety of actions. The phrase, "No," is spoken in varying volumes, the increasing loudness of which is relative to the dog's offense.

    Definition of Relativity
    relativity theory - (physics) the theory that space and time are relative concepts rather than absolute concepts

  14. I'm going to talk about how physics relate to soccer. When a ball is kick and it it goes the same way as the airflow it reduces the pressure from the ball and it starts to spin. This force makes the ball take different directions. http://www.youtube.com/watch?v=-t5MF7NRQh4

  16. Topspin is one of the most difficult and effective shots in Tennis. Topspin is when a player hits the ball in a way that the ball spins clockwise upwards, and falls to the ground before the opponent can react. It occurs due to a few laws of Physics.
    CONSERVATION OF MOMENTUM:
    This law states that the momentum, or mass times velocity, before a collision occurs is equal to the momentum after the collision.
    the equation for this law would be:
    (Mass of ball*velocity of ball)+(mass of racket*velocity of racket)=(mass of ball*velocity of ball after collision)+(mass of racket*velocity of racket after collision)
    ROTATIONAL MOMENTUM:
    This concept is the main reason why topspin is different from all other tennis strokes. The topspin shots rotate the ball while in it's trajectory, gives the tennis ball another factor in calculating it's velocity and position. The ball's rotation makes the ball spin, which gives it an additional velocity vector. This new velocity vector, called Angular Velocity, must be added to the linear velocity in order to calculate the true speed of the ball. Angular Velocity is equal to the linear speed divided by the radius of the tennis ball, and is also equal to the total number of rotations completed divided by the time in motion. We can calculate this new velocity vector with kinematics.
    NEWTON'S 3 LAWS OF MOTION:
    The game of Tennis is based upon Newton's Laws. These laws serve as a basis for our understanding of the topspin shot.
    Newton's 1st Law states that a body in motion tends to stay in motion, and a body at rest tends to stay at rest. The ball would not be able to travel across the court without this law.
    Newton's 2nd Law states that force is equal to mass times acceleration. We used this definition of force in the Kinematics section.
    Newton's 3rd Law states that every action has an equal but opposite reaction. The tennis ball would never bounce off the strings of the racket and travel over the net if this law did not exist.

  18. What interest me is volleyball. There are many way physics is related to volleyball. They are Projectile motion, Power, Work, Force, and Acceleration. This video talks about how serving is related to physics with work and acceleration. How bumping is related with projectile motion. Setting is related to it with force. And spiking is related to it with force and power.

  19. tennis relates to tennis in many ways like when a person spins the ball it hits the ground and goes a different way not straight. and when you top spin it it goes high then dives down and when it hits the court it goes faster then normal.

  20. What interests me the most that I can relate to physics, is hearing the sound of music. Almost everyone on this Earth loves hearing music. Some people can even play music really great. Since sound is the medium of music, most of the physics of music is the physics of sound. Music has five major themes related to physics. (Vibration, sound waves, frequency and pitch, resonance, and overtones) The following is a short definition of each term.

    Vibration- is the source of all sound

    Sound waves- are compression waves.

    Frequency and pitch- Sound waves have a frequency, which is the number of compression pulses that go past a fixed point in a given amount of time. The frequency of audible sound is measured in hertz, or cycles per second. In general, you perceive the frequency of the wave as a particular pitch.

    Resonance- If a vibration or sound wave can excite another object into vibrating, the second object is said to resonate.

    Overtones- An overtone is a natural resonance of a system. Systems described by overtones are often sound systems.

    Never thought of this right?
    Below is an example in a video,
