• all of the above

When two objects of the same weight traveling at different speeds collide head on, both objects

• stop moving.

• bounce backwards and change speeds

• change direction and move at their original speed

• bounce backward and travel at their original speed.

Which of the following collisions would cause a still object to move at the speed of the object that hit it?

• a collision of a moving object with a lighter still object

• a collision of a moving object with a heavier still object

• a collision of a moving object with a still object of the same weight

• a collision of a large, light object and a still object that is smaller, heavier

What happens when two objects collide?

• Energy is transferred from one object to another.

• Energy is created and the objects move faster.

• Energy is destroyed and the objects move slower.

What effects the amount of energy transferred in a collision?

• the speed and direction affects a collision

• the speed and the weight affect a collision

• the weight and direction affects a collision

• the direction and heat affects a collision
