Force and Motion

Front

What is Newton's Second Law of Motion?

Back

It states that 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 a force?

Back

A push or pull that is exerted on matter.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force of gravity acting on that mass.

Front

What is an unbalanced force?

Back

A force that results in a change in the motion of an object, causing it to accelerate.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What is the formula for calculating force?

Back

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

Front

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

Back

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

Front

What is the role of friction in motion?

Back

Friction is a force that opposes the motion of an object, acting in the opposite direction.

Front

What is gravitational force?

Back

The attractive force between two masses, such as the Earth and an object.

Front

How does mass affect weight?

Back

Weight increases as mass increases, due to the gravitational force acting on the mass.
