Front

What is the relationship between an object's weight and its mass?

Back

An object's weight is proportional to its mass.

Front

What is an example of an unbalanced force?

Back

A person on an elevator going down.

Front

Which of the following is NOT an example of circular motion?

Back

A car accelerating onto a highway.

Front

What is the force you have to overcome to start an object moving?

Back

Static friction.

Front

What force keeps a satellite in orbit?

Back

Centripetal force.

Front

Define weight in terms of mass and gravitational acceleration.

Back

Weight is the force exerted by gravity on an object, calculated as weight = mass × gravitational acceleration.

Front

What is static friction?

Back

Static friction is the force that must be overcome to start an object moving from rest.

Front

What is centripetal force?

Back

Centripetal force is the net force that acts on an object moving in a circular path, directed towards the center of the circle.

Front

How does an unbalanced force affect an object's motion?

Back

An unbalanced force causes an object to accelerate, changing its velocity.

Front

What is the difference between balanced and unbalanced forces?

Back

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