the rate of change in position
What is speed?
100
This changes an objects speed, or direction, or both.
What is a net force?
100
This is the force that every object in the universe exerts on every other object.
What is gravity?
100
if Kim won a 300 meter(m) race in 40 seconds(s), her rate of speed would be this.
What is 7.5 m/s
100
This is an object's tendency to resist any change in its position.
What is inertia?
200
This describes both speed and direction.
What is velocity?
200
a push or a pull that one body exerts on another body.
What is a force?
200
This determines the amount of gravitational pull on an object.
What is an object's mass?
200
If you want to calculate the acceleration of a car, you should do this to the change in velocity of the car by the time interval.
What is divide?
200
Newton's first law of motion states that an object at rest stays at rest unless this acts on it.
What is a net force?
300
A term used to indicate a decrease in speed.
What is acceleration?
300
The force the opposes motion between two surfaces that are touching.
What is friction?
300
The measure of the force of gravity on an oboject.
What is the object's weight?
300
If Ted won a 300 m race in 40 s, this would be his rate of speed.
What is 7.5 m/s?
300
A person in a car collision who is not wearing a seat belt continues to do this because of inertia.
What is continue to move forward at the same speed of the car?
400
the way to find average speed
What is distance divided by time?
400
These forces are equal in size and opposite in direction.
What are balanced forces?
400
Comparing the moon and the earth, this one has more gravitational pull.
What is the earth?
400
If Julia won a 600 m race in 80 s, this would be her rate of speed.
What is 7.5 meters per second? (7.5 m/s)
400
between a ping pong ball and a bowling ball, this object has more inertia.
What is a bowling ball?
500
The speed an object travels in a given moment in time.
What is instaneous speed?
500
The amount of gravitational force between two objects depends on this.
What are two objects masses and the distance between them?
500
The farther away a satellite is from earth, the less of this there is on it.
What is gravitational pull?
500
If you draw a time-distance graph you would place units of seconds on the x axis and units of this on the y axis.
What is distance? (or meters)
500
This is the rate of change of speed and/or direction.
