## Chapter Three(Speed, Velocity, and Acceleration) Vocabulary -Mr. Colabreeze

### Acceleration

The rate of change in velocity (a change in direction or a change in speed)
A rate of motion determined by dividing the total distance traveled by the total travel time
Forces that are equal in size and opposite in direction

### Average Speed

A rate of motion determined by dividing the total distance traveled by the total travel time
The rate of change in velocity (a change in direction or a change in speed)
Force exerted by every object in the universe on every other object.

### Balanced Forces

A rate of motion determined by dividing the total distance traveled by the total travel time
Forces that are equal in size and opposite in direction
Force exerted by every object in the universe on every other object.

### Constant Speed

The rate of change in velocity (a change in direction or a change in speed)
A rate of motion determined by dividing the total distance traveled by the total travel time
Speed that doesnt change

### Force

Speed that doesnt change
Forces that are equal in size and opposite in direction
A push or a pull one body exerts on another

### Gravity

Force exerted by every object in the universe on every other object
A rate of motion determined by dividing the total distance traveled by the total travel time
Forces that are equal in size and opposite in direction

### Inertia

The rate of motion at a given instant at time, such as that given on a car's speedometer
The rate of motion, or rate at which a body changes position
The tendency of an object to resist any change in its motion.

### Instantaneous Speed

The tendency of an object to resist any change in its motion.
The rate of motion, or rate at which a body changes position
The rate of motion at a given instant at time, such as that given on a car's speedometer

### Net Force

The tendency of an object to resist any change in its motion.
The sum of forces on an object when unbalanced forces are applied to it.
The measure of the force of gravity on an object

### Speed

The sum of forces on an object when unbalanced forces are applied to it.
The speed and distance of a moving body, such as a storm or a basketball thrown across a court
The rate of motion, or the rate at which a body changes position

### Velocity

The tendency of an object to resist any change in its motion.
The measure of the force of gravity on an object
The speed and distance of a moving body, such as a storm or a basketball thrown across a court

### Weight

The measure of the force of gravity on an object
The tendency of an object to resist any change in its motion.
The rate of motion at a given instant at time, such as that given on a car's speedometer
