8.1 Collisions Review

Front

True or False? Forces are applied on both objects unequally during a collision.

Back

False

Front

What influences an object's elastic limit?

Back

All influence an elastic limit: Its shape, thickness, and type of material.

Front

If the head wind increases, there will need to be _____ friction between tires and the road to keep the same amount of kinetic energy transfer between them.

Back

more

Front

A(n) _______ surface will produce more friction.

Back

rough

Front

True or False? Speed or mass increases before a collision lead to lower peak forces between objects during a collision.

Back

False

Front

What is the definition of a collision?

Back

A collision is an event where two or more bodies exert forces on each other for a relatively short time.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion.

Front

What is the relationship between mass and kinetic energy?

Back

Kinetic energy increases with the square of the velocity and is directly proportional to mass.

Front

What happens to momentum during a collision?

Back

Momentum is conserved in a closed system during a collision.

Front

What is the elastic limit?

Back

The elastic limit is the maximum extent to which a solid can be stretched without permanent deformation.
