200
An increase in velocity.
What is positive acceleration?
200
The unit to express force
What is a newton?
200
Force of gravity=mass of the object x gravity
How do you calculate gravitational force?
200
The measure of how much force is acting on a given area
What is pressure?
300
How far you have traveled on the whole path you took to a destination.
What is distance?
300
A decrease in velocity.
What is negative acceleration?
300
The combination of all the forces acting on an object

What is a pascal?
400
The straight-line distance between two positions.
What is displacement?
400
Acceleration in a circular motion
What is centripetal acceleration?
400
The acceleration of an object depends on the mass of the object and the amount of force applied
What is Newton's second law of motion?
400
When gravity pulls something down with no other forces acting on it.

400
density=mass/volume
How do you calculate density?
500
Total distance traveled divided by the time it took to travel that distance.
