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 at the same speed and in the same direction unless acted upon by an unbalanced force.

Front

What is inertia?

Back

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

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. (F = ma)

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

What is friction?

Back

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

Front

What happens to a ball rolling on the ground when friction acts on it?

Back

Friction slows down and eventually stops the ball.

Front

What is a balanced force?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

Front

What is an unbalanced force?

Back

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

Front

What happens to an object in space when no forces act on it?

Back

It will continue to move at the same speed and in the same direction.

Front

What is gravity?

Back

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