Tension And Acceleration

Air Track Accelerations
These videos are of a slider on an air track. A string is connected to the slider and runs over a pulley. A given mass is connected to the string and hangs over the pulley. The hanging mass accelerates the slider across the air track during an interval of time. There are three sets of movies. One has the tension force constant, one has the slider mass constant, and the other attempts to keep the slider acceleration constant.

Some apects to keep in mind are:

1. How does tension affect the acceleration?
2. How does the mass of the cart affect acceleration?
3. How is Newton's second law related to these video clips?

Gravity and Air Resistance

Ball Drop
These video clips show two different balls(a tennis ball and a red kick ball) being dropped to the floor inside a building and off a bridge outside a building. There is no initial velocity, the ball is just simply dropped. The tennis ball and red kick ball have different masses

Some possible questions to ask are:

1. Does air resistance act on these balls as they fall to the floor or ground?
2. Is the velocity constant?
3. What is the acceleration of the ball?
4. What should the acceleration be if no air resistance acts on the ball?
5. What effect does mass of the ball have on acceleration and velocity?

Filter Drop
These videos show a different number of coffee filters being dropped to the floor. Air resistance acts on them to give them a constant velocity which relates to terminal velocity. The area is always the same, but the mass increases with more filters. There are 2, 4, 6, and 8 filter drops.

Some possible questions to ask are:

1. What is the terminal velocity and when does it reach it?
2. What effect does the number of filters have on the motion?

Galileo's Ball Drop
This video clip simulates Galileo's boat experiment. We fastened a ladder in the box of a truck to simulate the mast on a ship. The truck moves at constant velocity while we drop a shot put to the ground. We chose a shot put because we felt it would be least affected by air resistance due to its size and shape.

Some apects to keep in mind are:

1. Where does the shot hit the ground compared to where it was released? Why is this so?
2. What makes this experiment like Galileo's boat experiment?
3. What is the horizontal velocity component of the shot? How does this compare to that of the truck?

Projectile Motion

Basketball Shot
These basketball clips show a basic free throw type shot. They are intended to show projectile motion. Believe me, it took a long time to "make" these clips!

Some possible questions to ask are:

1. Based on what you see in the video, what are some sources of error?
2. Is it truly projectile motion and why?

Projectile Truck

These clips are involved with throwing a soccer ball out of the back of a moving pickup truck. Two cases are considered. In one, the ball is thrown vertically upward from the point of view of a person sitting in the truck. In the second case, the ball is projected horizontally away from the truck.


Some possible questions to ask are:
  1. Describe the motion of the ball from the point of view of someone standing on the road and also the person on the truck.
  2. When thrown vertically, does the ball experience any horizontal motion other than that caused by the truck?
  3. Does the Galilean velocity transformation relationship correctly describe the ball's velocity?

Shuttlecock
These video clips show a shuttlecock being hit with a racket. These videos were shot on a stage inside an auditorium. The black curtains provided a very good uniform background to clearly show the shuttlecock. We used the stage lights as a good source of light.

Some questions to keep in mind are:

1. Does the shuttlecock have a constant horizontal velocity? What does this suggest?
2. Does the shuttlecock follow projectile motion?
3. What is the acceleration in either direction?

Waves
Rubber Tube
These videos show a wave pulse moving through a piece of rubber tubing. The rubber tubing has a tension applied to it by use of a spring scale. Different tensions are applied to see the effect of it.

Some possible questions to ask are:

1. What effect does the tension have on the velocity of the wave pulse?
2. What is the relationship between tension and velocity based on an equation?
3. What is the linear density of the rubber tubing?

Ripple Tank
These videos show waves in a ripple tank. Our setup used a point light source under the tank to project the waves on the ceiling onto white paper. We set up the video camera to tape the waves on the ceiling. We did some different things with the ripple tank like vary the frequency by changing the voltage of the wave source. We also changed the water depth to show the effect on velocity. One video is of a wave traveling over a piece of plastic that we put in the water to change the depth in one spot.

Some possible questions to ask are:

1. What is the effect of water depth on velocity?
2. What happens to the wavelength as frequency is increased?
3. What happens to the angle of the wave pulse as it travels over the piece of plastic?

Slinky Waves
These videos involve waves produced with a slinky. We used a high-speed digital video camera to record these videos.
