Newton's Three Laws of Motion

Front

What is Newton's First 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 Second 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 as the formula: Force = Mass x Acceleration.

Front

What is Newton's Third Law of Motion?

Back

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

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 an object's 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 the formula for calculating force?

Back

Force = Mass x Acceleration.

Front

If a car is moving at a constant speed, what can be said about the forces acting on it?

Back

The forces acting on the car are balanced.

Front

What happens to an object when a net force is applied?

Back

The object will accelerate in the direction of the net force.

Front

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

Back

A larger mass requires a greater force to achieve the same acceleration as a smaller mass.

Front

What is inertia?

Back

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