Understanding Motion, Position, and Direction

Front

What is the location of an object described by?

Back

Position is described by both distance and direction.

Front

What is the force that occurs when one object rubs against another?

Back

Friction is a force that occurs when one object rubs against another; smooth surfaces have less friction.

Front

What are forces that cancel each other out when acting together on an object called?

Back

Balanced forces are forces that cancel each other out when acting together on an object.

Front

How is the amount of space between two objects or places measured?

Back

Distance can be measured in mm, cm, m, or km.

Front

What tells which way a line points from one object or place to another?

Back

Direction tells which way a line points from one object or place to another; examples include north, up, right, forward.

Front

What is motion?

Back

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

Front

What is speed?

Back

Speed is the distance an object travels in a certain amount of time.

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to move or change its motion.

Front

What is an example of balanced forces?

Back

An example of balanced forces is two people pushing a car in opposite directions with equal strength.

Front

What is the difference between distance and displacement?

Back

Distance is the total path traveled, while displacement is the shortest path from the starting point to the endpoint.
