### Sliding Friction

When an object rolls over a surface
Friction when one solid surface slides over another
When an object moves through a liquid

### Define the following: Reference Point

A place or object used for comparison to determine if an object
is in motion
A unit of pressure equal to one Newtown per square meter
The potential energy stored in the nucleus of an atom

### Centripetal Force

Any force that causes an object to move in a circle
any force that causes an object to move in a square
Any force that causes an object to move in one direction and one line

### Net Force

The overall time of a moving object with multiple forces
A non moving action that doesn't affect the object
The overall force of an object when all the individual forces are acting on an object added together

### Motion

The state in which one object's distance from another is not changing
The state in which one object's distance from another is changing
The state in which one object's time and length from another is changing

### Speed

The time and object travels in one unit of time
The distance an object travels in one unit of time
The mass of an object that travels in a constant unit of time

### Rolling Friction

When an object rolls over a surface
Friction when one solid surface slides over another
When an object moves through a liquid

### Terminal Velocity

The lowest heat an object reaches
The greatest velocity and object reaches
The median weight an object reaches

### Projectile

An object that is thrown
An object that is measured
An object that is used for an experiment

### Velocity

Mass gained in a given time
Weight in a constant measure
Speed in a given direction

### Balanced Force

Equal forces acting on an object in the same direction
Equal forces acting on an object in different directions
Equal forces acting on an object in different time sequences

### Meter

### Newton Unit

1kg x 1m/s, ISU of force
2kg x 1m/s, ISU of energy
1kg x 4m/s, ISU of weight

### Gravity

The force that pulls objects toward each other
The force that pushes objects away from each other
The force that pulls objects above each other

### Liquid Friction

When an object rolls over a surface
Friction when one solid surface slides over another

### Law of Conservation of Momentum

Total energy of objects in an interaction does not change unless brought upon unbalanced force
Total momentum of objects in an interaction changes constantly
Total momentum of objects in an interaction does not change

### Force

An extended about of time put in the object
A push or pull extended on an object
A non moving action that doesn't affect the object

### Friction

the amount of energy that is gravitating towards an object
the time that one surface moves with an object at the same time
the force that one surface exerts on another when the two rub against each other

### Free Fall

The motion of a stationary object when the only force acting on it is heat
The motion of a falling object when the only force acting on it is gravity
The motion of a object at rest when the only force acting on it is pressure

### Unbalanced Force

An unbalanced force is a force that has three force stronger than any opposing forces
