Newton's 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 at a constant velocity 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 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 (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 the role of friction in motion?

Back

Friction is a force that opposes the motion of an object, causing it to slow down or stop.

Front

How does mass affect inertia?

Back

The greater the mass of an object, the greater its inertia.

Front

What is gravitational force?

Back

Gravitational force is the attraction between two objects due to their mass.

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 opposite, causing a change in the motion of an object.

Front

What happens to an object in free fall?

Back

An object in free fall experiences only the force of gravity, leading to acceleration downwards.
