When is an object in motion?

When its position changes.

100

What is speed and what does rate tell you the amount of?

Speed is the distance the object moves per unit of time. The rate tells you the amount of something that occurs or changes in one unite of time.

100

What does Newtons first law state?

An object at rest will remain at rest unless acted by a net force.

100

What does a constant slope represent?

Motion and constant speed.

200

What are some reference points?

tree,stop sign,and a building are good examples.

200

What is the equation in which you calculate speed?

Speed equals distance/time

200

What is resistant to change in motion?

inertia.

200

A force is described by its what two things?

By its strength an direction.

300

What happens when one object pushes or pulls another object?

the first object exerts a force on the second object.

300

What could happen if there is an error in velocity,either in speed and direction?

a collision

300

Which of Newtons law stated the size and direction of a net force equals the mass times acceleration?

Second law.

300

What happens when you multiply mass and acceleration?

You find out that force is measured in kilograms.

400

A force that pulls objects toward each other is a result of what?

A result of mass.

400

List the different ways an object could accelerate

increases speed,decreases speed, or changes direction

400

Acceleration is measured in?

Meters per second.

400

The more mass an object has the greater the what?

the greater the gravitational force between it and another object

500

Whats the reason why there is a nonzero net force on a object.

since the forces on the object are unbalanced

500

what is the equation for calculating acceleration?

acceleration=final speed-initial speed/time

500

If one object exerts force what does the second object do?

The second object exerts a force of equal strength.

500

Mass is a measure of what?

of the amount of matter in an object.
