Newton's Laws of Motion

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 Newton's Second Law of Motion?

Back

Force = Mass × Acceleration (F = ma). This law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

What is Newton's Third Law of Motion?

Back

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

Front

What is a balanced force?

Back

Forces that are equal in size and opposite in direction, resulting in no change in motion.

Front

What is an unbalanced force?

Back

Forces that are not equal and opposite, resulting in a change in motion.

Front

What is net force?

Back

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

Front

How do you calculate acceleration?

Back

Acceleration = Net Force / Mass.

Front

What happens to an object when the net force acting on it is zero?

Back

The object will remain at rest or continue to move at a constant velocity.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

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

Back

As mass increases, acceleration decreases if the net force remains constant.
