### collision-elastic-2.iwp

Two gliders collide in an elastic collision. The red glider is initially stationary. The x-coordinate of the center of mass of the system of gliders is shown as a black dot. Play the animation. Click ..

### collision-elastic-3.iwp

Two gliders collide in an elastic collision. The x-coordinate of the center of mass of the system of gliders is shown as a black dot. Play the animation. Click Show Graph. The velocities of the ..

### collision-elastic-4.iwp

What is the total momentum of this system? Why can't you use the law of conservation of momentum to calculate what the velocities of both objects after the collision are? There is nevertheless a way ..

### collision-inelastic-01a.iwp

Answer these questions using the animation. The grid spacing in meters is given in the upper right, and the elapsed time and masses of the objects are given under Outputs. 1. What is the velocity before ..

### collision-inelastic-01b.iwp

Check your answers. Velocities and momenta are given under inputs and outputs. Click on Show Graph for velocity vs. time graphs.

### collision-inelastic-02a.iwp

Two objects collide and stick together. The animation stops as the collision starts. You are to predict the velocity after collision of the combined blocks. Use the fact that the total momentum is conserved. This ..

### collision-inelastic-02b.iwp

Check your answers. Velocities and momenta are given under inputs and outputs. Click on Show Graph for velocity vs. time graphs.

### collision-inelastic-03a.iwp

Two objects collide and stick together. The animation stops as the collision starts. Use conservation of momentum to predict the velocity after collision of the combined blocks. Also sketch the velocity vs. time graph for ..

### collision-inelastic-04a.iwp

One object moving left collides with another moving right. They stick together in the collision. The animation stops as the collision starts. Use conservation of momentum to predict the velocity after collision of the combined ..

### collision-inelastic-05.iwp

Create a collision where the combined blocks move to the left after the collision. You can change masses, positions, and initial velocities. After changing the inputs, click the Reset button before playing. Use conservation of ..

### collision-inelastic-template.iwp

Two objects collide and stick together.

### collision-symmetric.iwp

Two gliders of equal mass collide in an elastic collision. Play the animation. Click Show Graph. The velocities of the two objects will be displayed as a function of time. Try collisions for different pairs ..

### finalke-03.iwp

1. Two dimunitive cars, initially at rest, are subjected at t =0 to an identical and constant force in the +x direction. How do the kinetic energies (see outputs) of the two cars compare after traveling the ..
