Force and 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 an unbalanced force?

Back

A force that causes an object to change its state of motion (i.e., to accelerate).

Front

Define force in physics.

Back

A push or pull that is exerted on matter.

Front

What is inertia?

Back

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

Front

What does Newton's Third Law of Motion state?

Back

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

Front

Give an example of Newton's Second Law of Motion in everyday life.

Back

A truck needs a more powerful engine than a small car to accelerate.

Front

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

Back

It accelerates in the direction of the net force.

Front

What is the relationship between mass and acceleration according to Newton's Second Law?

Back

As mass increases, acceleration decreases if the same force is applied.

Front

What is the effect of gravity on an object in motion?

Back

Gravity pulls objects downward, affecting their motion and speed.

Front

How does friction affect motion?

Back

Friction opposes the motion of an object, slowing it down or stopping it.
