Contact Forces

Front

What happens to the strength of contact forces when two objects make contact during a collision?

Back

They become equal but in opposite directions.

Front

What factors influence how much a solid object deforms for a given force?

Back

Material, Shape and Thickness.

Front

How does an increase in the speed or mass of a moving object affect the peak forces applied during a collision?

Back

It increases the peak force.

Front

What is the term for a change in shape due to force (push or pull)?

Back

Deform.

Front

Which of the following is NOT a factor that can cause objects to be damaged or not in a collision?

Back

Color.

Front

What is a contact force?

Back

A force that acts at the point of contact between two objects.

Front

What is the difference between elastic and inelastic deformation?

Back

Elastic deformation is reversible, while inelastic deformation is permanent.

Front

What is the elastic limit?

Back

The maximum extent to which a solid can be stretched without permanent deformation.

Front

What is a collision?

Back

An event where two or more bodies exert forces on each other for a relatively short time.

Front

What is the role of friction in contact forces?

Back

Friction opposes the motion of objects in contact.
