CMS 6th Grade Physical Science Review

Front

What does it mean for an object to be in motion?

Back

An object is in motion if its position changes relative to another object.

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state, such as a skier at the top of a hill.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, such as a car driving down a hill.

Front

What happens to an object at rest when a force is applied?

Back

The object will start to move, changing its position relative to other objects.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, indicating that it is speeding up or slowing down.

Front

What is a frame of reference?

Back

A frame of reference is a set of criteria or stated values in relation to which measurements or judgments can be made.

Front

What does it mean for an object to be stationary?

Back

An object is stationary if its position does not change relative to another object.

Front

How does friction affect motion?

Back

Friction is a force that opposes motion, slowing down or stopping moving objects.

Front

What is the difference between speed and velocity?

Back

Speed is the distance traveled per unit of time, while velocity includes both speed and direction.

Front

What is the law of conservation of energy?

Back

The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.
