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 an unbalanced force.

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 does it mean for forces to be unbalanced?

Back

Unbalanced forces are not equal and can cause an object to start moving, stop moving, or change direction.

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 = m x a).

Front

What is the formula for calculating force?

Back

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

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

How does mass affect acceleration according to Newton's 2nd Law?

Back

Greater mass requires more force to achieve the same acceleration.

Front

What is the law of universal gravitation?

Back

Every mass attracts every other mass with a force that is proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

Front

What is an example of Newton's 1st Law in everyday life?

Back

A book resting on a table will remain at rest until someone pushes it.
