Understanding Forces and Motion Flashcard

Front

What does a horizontal line on a motion graph indicate?

Back

The object is stopped.

Front

Which factor does not affect the motion of an object?

Back

Color.

Front

Why does a heavier object require more force to move than a lighter object?

Back

Because it has more mass.

Front

How do you calculate speed?

Back

Speed = Distance / Time.

Front

If a car travels 100 meters in 10 seconds, what is its speed?

Back

10 m/s.

Front

What happens to the force needed to change an object's motion if its mass increases?

Back

The force needed increases.

Front

What is friction?

Back

Friction is a force that opposes motion between two surfaces in contact.

Front

What is gravity?

Back

Gravity is the force that pulls objects toward each other, such as the Earth pulling us down.

Front

What is mass?

Back

Mass is the amount of matter in an object, usually measured in kilograms.

Front

What is motion?

Back

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