energy and collision

In the picture you can see a car has collided with a stop sign. Where does the energy from the car go?

• All the energy from the car passes to the stop sign

• None of the energy from the car passes to the stop sign

• All of the energy from the car passes to the air

• The energy from the car is shared between the car, the stop sign, the air and the road.

Look at the picture of the Newton's Cradle. When ball 1 is released it collides with the other balls and energy is transferred. Ball 6 will swing upwards and fall back down and collide with the other balls. After some time ball 6 will reduce its swing upwards.

• Because ball 6 has the same amount of energy

• Because ball 6 will have more energy and go higher

• Because ball 6 has lost energy

Which of the following would transfer more energy?

• Lowering ball 1 before release

• Raising ball 1 higher before release

• Gently putting ball 1 down next to ball 2

• Keeping ball 1 in the same place
