Forces and Motion Test

Front

What is net force?

Back

The overall force acting on an object after all the forces are combined.

Front

What does a negative acceleration indicate?

Back

It means that the object is slowing down.

Front

What is a force?

Back

A push or pull acting on an object.

Front

How do you calculate acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time.

Front

What is the unit of force?

Back

Newton (N).

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces do not change an object's motion, while unbalanced forces cause acceleration.

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 net force?

Back

Net Force = Total Forces acting in one direction - Total Forces acting in the opposite direction.

Front

What is the effect of air resistance on falling objects?

Back

Air resistance opposes the motion of falling objects, reducing their acceleration.

Front

What is the relationship between mass and acceleration?

Back

According to Newton's second law, acceleration is inversely proportional to mass when force is constant.
