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 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 is directly proportional to the net force acting on it and inversely proportional to its mass. This is often expressed as F = ma.

What is Newton's 3rd Law of Motion?

Back

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

What is the unit of force?

Back

Newtons (N) are the units used to measure force.

Front

What is inertia?

Back

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

Front

What happens to an object when the forces acting on it are balanced?

Back

The object remains in its current state of motion, whether at rest or moving at a constant velocity.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, acting parallel to the surface of contact.

Front

What is an example of Newton's 3rd Law in action?

Back

A soccer ball hitting a goal post; the ball exerts a force on the post, and the post exerts an equal and opposite force on the ball.

What is the effect of unbalanced forces on an object's motion?

Back

Unbalanced forces cause an object to accelerate in the direction of the net force.

What is the role of gravity in motion?

Back

Gravity is a force that pulls objects toward each other, affecting their motion, especially in free fall.
