Newton's Laws

Front

What is Newton's 1st 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 a net external force.

Front

What is Newton's 2nd 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. (F = ma)

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

What are balanced forces?

Back

Forces that are equal in size and opposite in direction, resulting in a net force of zero.

Front

What are unbalanced forces?

Back

Forces that are not equal and opposite, resulting in a net force that causes an object to accelerate.

Front

What is inertia?

Back

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

Front

What is the formula for calculating force?

Back

Force (F) = mass (m) × acceleration (a).

Front

What is an example of a balanced force?

Back

Two people pushing a car in opposite directions with equal force.

Front

What is an example of an unbalanced force?

Back

A soccer player kicking a ball, causing it to move in the direction of the kick.

Front

What is the net force?

Back

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