Newtons 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 is Newton's 2nd Law of Motion?

Back

The acceleration of an object depends on the mass of the object and the amount of force applied. It can be expressed with the formula F = ma (Force = mass x acceleration).

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

What unit is used to measure force?

Back

Newtons (N).

Front

If an object has more mass, what happens to the force needed to accelerate it?

Back

It takes more force to accelerate an object with more mass.

Front

What is the formula to calculate force?

Back

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

Front

What is the acceleration of an object if a force of 200 N is applied to a mass of 20 kg?

Back

Acceleration = Force / Mass = 200 N / 20 kg = 10 m/s².

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 happens to an object in motion if no net force acts on it?

Back

It will continue to move at a constant velocity.

Front

What is inertia?

Back

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