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

Front

What is Newton's Third 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 the formula to calculate force?

Back

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

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 does it mean for forces to be unbalanced?

Back

Unbalanced forces result in a change in motion, causing an object to accelerate.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, caused by the contact between two surfaces.

Front

How does mass affect acceleration?

Back

According to Newton's Second Law, as mass increases, acceleration decreases if the same force is applied.

Front

What is the relationship between force, mass, and acceleration?

Back

The relationship is described by Newton's Second Law: F = ma.
