Which house has damage?
Which picture shows a contact force?
This cup has gone above its elastic limit. Why?
Look at the picture. The angry boy is applying a force to the chair.
Is the chair deforming?
How could you decrease the damage in this collision?
What is true about the forces in the collision between the soccer player's head and the ball?
What happens to the ball when the player's head applies a force to it?
If the speed of the ball increased, what would happen to the forces in the collision?
Draw a free body diagram for the ball.
You only need to draw 1 force.
Before the collision, which objects had kinetic energy?
How could you increase the kinetic energy of the ball?
Look at the graphs. Graph 1 shows how mass affects kinetic energy. Graph 2 shows how speed affects kinetic energy.

Graph 2
If you wanted to increase the kinetic energy of the ball more, what should you do?
A different player gets hit by a tennis ball. The speed of the tennis ball is the same as the soccer ball, but the mass of the tennis ball is less (smaller) than the mass of the soccer ball. How are the forces in this collision different than the soccer ball and head collision?
