Forces and Newton's Laws

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 with the same speed and in the same direction unless acted upon by an unbalanced force.

Front

Define force.

Back

A push or pull on an object that can cause it to accelerate.

Front

What is the formula for calculating force?

Back

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

Front

What does it mean for forces to be balanced?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object.

Front

What is Newton's Second Law of Motion?

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 an unbalanced force?

Back

An unbalanced force is a force that causes an object to change its state of motion.

Front

What is Newton's Third Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

What is mass?

Back

Mass is the amount of matter in an object, typically measured in kilograms.

Front

How does mass affect acceleration?

Back

The greater the mass of an object, the less acceleration it will have when a given force is applied.
