Collision

What happens when two objects collide?

• The heavier object reacts stronger

• The slower object breaks

• The smaller object turns out okay

• Energy of one object is transferred to the other

What happened when the speed increased in the bubble collision experiment?

• Less energy was transferred

• More energy was transferred and the distance increased

• No energy change was seen

• The energy caused the bubbles to pop

What happened when more weight was added to the bubble collision experiment?

• More weight meant more energy was transferred

• No energy change was seen

• The weight did not affect the experiment

• The weight caused the bubbles to pop

When two objects collide their motion changes. Why does this happen?

• energy was transferred from one object to the other

• their gravity changed

• the objects lose mass

• pe= mxgxh

• p=mxv

What is the principle of conservation of momentum in a collision?

• Momentum is always lost in a collision

• Momentum is always gained in a collision

• Total momentum before and after a collision is the same

• Momentum is irrelevant in a collision

In an elastic collision, what happens to the kinetic energy?

• It is completely lost

• It is partially lost

• It is conserved

• It is doubled
