Newtons Laws of Motion

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 unless acted upon by a net external 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. (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 is inertia?

Back

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

Front

What is friction?

Back

Friction is a force that opposes the motion of an object.

Front

What is gravity?

Back

Gravity is the force that pulls objects toward each other, such as the Earth pulling us down.

Front

What happens to a ball rolling on the ground when friction is present?

Back

Friction slows down and eventually stops the ball.

Front

If you push a heavy object and a light object with the same force, which one will move faster?

Back

The light object will move faster because it has less mass.

Front

What is the formula for calculating force?

Back

Force = Mass x Acceleration.

Front

What does it mean when we say 'action and reaction'?

Back

It means that for every force exerted, there is a force of equal size but opposite direction acting back.
