Unit 4: Contact Forces Study Guide

Front

What surface absorbs the most during a collision?

Back

Sand absorbs the most during a collision.

Front

What is the relationship between mass and applied force for the same acceleration?

Back

Larger masses require more force to reach the same acceleration as smaller masses.

Front

Newton’s Second Law states; Force is equal to mass times _________.

Back

acceleration

Front

How does mass affect acceleration when force is applied?

Back

Mass decreases acceleration.

Front

Is this statement true? 'This is Newton's 2nd law.'

Back

False.

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

Define force in the context of physics.

Back

Force is a push or pull on an object resulting from the object's interaction with another object.

Front

What is the unit of force in the International System of Units (SI)?

Back

The unit of force is the Newton (N).

Front

What does acceleration depend on according to Newton's Second Law?

Back

Acceleration depends on the net force acting on an object and the mass of the object.

Front

What happens to acceleration if the mass of an object increases while the force remains constant?

Back

Acceleration decreases.
