Elastic and Inelastic Collision Examples

By Mr. Castillo

Multiple Choice

While playing pool, Emma notices that the pool balls bounce apart.  What type of collision is this?

• Elastic
• Inelastic
• Explosive
• Force

Multiple Choice

Jorge noticed a collision outside the coffee shop where two cars collided and stuck together.  What type of collision did he observe?

• Elastic
• Inelastic
• Completely inelastic
• none

Multiple Choice

Many factors can affect what happens when balls collide. For example, the material the ball is made from, how hard the balls hit each other, whether both balls are moving, and the directions they are moving in.

If two tennis balls are moving towards each other at the same speed what do you expect to observe (see)?

• Both balls stop moving

• One tennis ball will stop and the other will keep moving

• One tennis ball will jump over the other ball

• Both balls bounce off each other

Multiple Choice

What happens when two objects collide?

• Energy is changed into force.

• Energy is transferred from one object to another.

• Energy is created and the objects move faster.

Multiple Choice

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

• stop moving.

• bounce backward and travel at their original speed.

• change direction and move at their original speed.

Multiple Choice

2 balls collide and bounce off of each other. During the collision total momentum remained constant and total kinetic energy remained constant. What type of collision is this?

• Inelastic Collision

• Elastic Collision

• Perfectly Inelastic Collision

• No collision occurred

Multiple Choice

Two carts collide. They stick together and continue moving. Is momentum conserved in this interaction?

• Yes

• No

Multiple Choice

The momentum of an object depends upon the object's ___________&_____________.

• size and shape

• mass and speed

• mass and veloctiy

• mass and energy

Multiple Choice

This picture is an example of ____________

• Elastic Collision
• Inelastic collision

Multiple Choice

A person is firing a cannon. What kind of "collision" is this?

• Elastic

• Moving Separation

• Recoil

Multiple Choice

Collisions where objects BOUNCE apart.

• inelastic collisions

• elastic collisions

• explosions

• none of these

Multiple Choice

A collision occurs when ...

• two or more objects hit each other with a force.

• an object in motion stays in motion.

• when an object at rest stays at rest.

Multiple Select

Select all the examples of collisions.

• car crash

• baseball bat hitting a baseball

• your fingers pushing the keys on a keyboard

• a car running at a fast speed

Multiple Choice

In a two-body collision,

• momentum is always conserved

• kinetic energy is always conserved

• neither momentum nor kinetic energy is conserved

• both momentum and kinetic energy are always conserved

Multiple Choice

What is an elastic collision?

• An elastic collision is an encounter between two bodies in which the total kinetic energy of the two bodies is different.

• An elastic collision is an encounter between two bodies in which the total kinetic energy of the two bodies remains the same.

• An inelastic collision is an encounter between two bodies in which the total kinetic energy of the two bodies remains the same.

Multiple Choice

What is an inelastic collision?

• When two objects collide, becoming stuck together and internal kinetic energy is lost (but not really lost, it transfers to different forms of energy)

• When two objects collide, becoming stuck together and internal kinetic energy is lost

• When two objects don't collide, becoming stuck together and internal kinetic energy is lost (but not really lost, it transfers to different forms of energy)

Multiple Select

What two variables effect momentum?

• mass

• weight

• height

• Velocity
