Forces and Newton's Laws

Front

What are the units for acceleration?

Back

m/sec²

Front

Which of Newton's laws states that a football on the ground will not move until someone kicks it?

Back

Newton's 1st Law

Front

What is the force that opposes motion between two surfaces in contact?

Back

Friction

Front

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

Back

Inertia

Front

What does Newton's 1st Law state?

Back

An object in motion (or at rest) will stay in motion (or at rest) until an outside force acts upon it.

Front

What is the formula for calculating force?

Back

Force = Mass x Acceleration (F = m*a)

Front

What is inertia?

Back

Inertia is the property of matter that causes it to resist changes in its state of motion.

Front

What is friction?

Back

Friction is a force that opposes the relative motion of two surfaces in contact.

Front

What is Newton's 2nd Law?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

What is the relationship between mass and acceleration according to Newton's 2nd Law?

Back

As mass increases, acceleration decreases if the force is constant.
