Force

A push or pull exerted on an object.

1

Newton

A unit of measure that equals the force required to accelerate 1 kilogram of mass at 1 meter per second per second.

2

Net force

The overall force on an object when all the individual forces acting on it are added together.

3

Friction

The force that two surfaces exert on each other when they rub against each other

4

Static Friction

Friction that acts between objects that are not moving.

5

Fluid Friction

Friction that occurs as an object moves through a fluid.

6

Rolling friction

Friction that occurs when an object rolls over a surface.

7

Gravity

The attractive force between objects; the force that moves objects downhill.

8

Mass

A measure of how much matter is in an object.

9

Weight

A measure of the force of gravity acting on an object.

10

Inertia

The tendency of an object to resist a change in motion.

11

Momentum

The product of an object’s mass and velocity.

12

Law of conservation of momentum

The rule that in the absence of outside forces the total momentum of objects that interact does not change.

13

Free fall

The motion of a falling object when the only force acting on it is gravity.

14

Satellite

Any object that orbits around another object in space.

15

Centripetal force

A force that causes an object to move in a circle.

16

Buoyant Force

The upward force exerted by a fluid on a submerged object.

17

Sliding Friction

Friction that occurs when one solid surface slides over another.
