One of these: force, inertia, speed, or weight causes acceleration.
What is force
100
This can cause a change in acceleration and/or velocity.
What is a force?
100
An object at rest remains at rest unless a force is acted upon it, an object in motion remains in motion unless a force is acted upon it.
What is Newton's First Law of Motion?
100
These are the measurements you would need to measure speed.
What is distance traveled and time it took to travel that distance?
200
A change in speed or direction of an object during a certain time frame
What is accleration
200
The measurement of the force of gravity on an object.
What is weight
200
Two cars are driving the same speed but in opposite directions, which means they have different ____________.
What is velocity?
200
The more mass an object has the greater the force needed to accelerate it.
What is Newton's 2nd Law of Motion (part 2)
200
Objects in a vacuum fall at the same rate.
What is free fall?
300
The property of matter that keeps a moving object wanting to stay in its original position.
What is inertia
300
The change of position during a unit of time
What is speed
300
It can be described as a pull, a push or a lift.
What is a force?
300
Acceleration is produced when a force is acted upon an object.
What is Newton's 2nd Law of Motion (part 1)?
300
The amount of matter an object has.
What is matter?
400
A force that acts between all masses
What is gravity
400
Speed with direction.
What is velocity
400
45 miles per hour is an example of _____________.
What is speed?
400
England.
What is where Newton is from?
400
A magician pulled a table cloth out from under a set of dishes. The dishes did not move. You concluded that you just observed this property of matter.
What is inertia?
500
The speed and direction of an object.
What is velocity?
500
A train started at 0 m/s and ended at 75 m/s over a 25 second period. What are you trying to find?
What is accleration?
500
They are both a change in speed during a certain time frame even though one may be negative and one may be positive.
What is acceleration and deceleration?
500
Unit of measure used for force.
What is a Newton (kg x m/s^2)
500
Suzie weighs 80 pounds. Billy weighs 100 pounds. They went to another far away planet, when they got there Suzie only weighed 40 lbs. and Billy 50lbs. Their ________ is the same however, thier ________ is different because of gravity.
