Which house has damage?
Which picture shows a contact force?
This cup has gone above its elastic limit. Why?
It will change back to how it was before.
It has deformed permanently and will not change back to how it was before.
It is completely broken because it is past its breaking point.
Look at the picture. The angry boy is applying a force to the chair.
Is the chair deforming?
No.
Yes.
Maybe; it depends on the size of the force.

What is true about the forces in the collision between the soccer player's head and the ball?
The force on the head is equal to the force on the ball.
The force on the head is bigger than the force on the ball.
The force on the head is smaller than the force on the ball.
What happens to the ball when the player's head applies a force to it?
The ball breaks.
The ball deforms.
The ball gets bigger.
The ball is happy. 🙃
If the speed of the ball increased, what would happen to the forces in the collision?
They would decrease.
They would stay the same.
They would increase.
Before the collision, which objects had kinetic energy?
The ball.
The head.
The ball and the head.
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?
Increase the mass.
Increase the speed.
It does not matter; mass and speed have equal effects on kinetic energy.
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. Why are the forces in this collision different than the soccer ball and head collision?
They are smaller.
They are the same.
They are bigger.
