Chapter 2 Laws of Motion

Front

What is the equation to calculate momentum?

Back

p = mv

Front

Define force.

Back

A force is a push or a pull upon an object resulting from the object's interaction with another object.

Front

What can be said about the forces acting on a car moving at a constant speed on a straight road?

Back

The net force is zero.

Front

What is the tendency of an object to resist changes in its motion?

Back

Inertia

Front

What type of force acts between two magnets?

Back

Noncontact force

Front

What is the formula for calculating acceleration?

Back

a = (vf - vi) / t

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

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

Back

Newton (N)

Front

What does the term 'net force' refer to?

Back

The overall force acting on an object after all the forces are combined.

Front

What is the relationship between mass and acceleration in Newton's Second Law?

Back

F = ma (Force equals mass times acceleration).
