Physical Science Review

Front

What is friction?

Back

Friction is a force that opposes the motion of an object when it comes into contact with another surface.

Front

What is an insulator?

Back

An insulator is a material that does not allow electricity or heat to pass through it easily. Example: rubber.

Front

What are balanced forces?

Back

Balanced forces are two forces acting in opposite directions on an object, and they are equal in size, resulting in no change in motion.

Front

What happens to particles when a substance is cooled?

Back

When a substance is cooled, its particles slow down and move closer together.

Front

What is gravity?

Back

Gravity is a force that pulls objects toward the center of the Earth or any other celestial body.

Front

What is motion?

Back

Motion is the change in position of an object over time.

Front

What is work in physics?

Back

Work is done when a force causes an object to move in the direction of the force.

Front

What is displacement?

Back

Displacement is the shortest distance from the initial to the final position of an object, along with the direction.

Front

What is an example of a conductor?

Back

An example of a conductor is metal, which allows electricity to flow through it easily.

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.
