A measure of how fast something moves a particular distance (for example, meters) over a given amount of time (for example, seconds).
The rate of change of the position of an object, or how far something will move in a given period of time.
What is speed?
100
Have a magnitude (strength) and a direction
What are forces?
100
“The velocity of an abject will remain constant unless a net force acts on it.”
What is Newton's First Law/ Law of Inertia?
100
The ______ of the line can tell the relative speed of the object.
What is slope?
100
Can be calculated by dividing the total distance the object travels by the total amount of time it takes to travel that distance.
What is average speed?
200
If an object is in motion and more force is applied to it, the object will begin moving _________.
What is faster?
200
If a heavy (more massive) object is in motion, more force must be applied to get the object moving ________.
What is faster?
200
“When one object exerts a force on a second object, the second one exerts a force on the first that is equal in magnitude and opposite in direction.”
What is Newton's Third Law?
200
The line, or path along which something is moving, pointing, or aiming.
What is direction?
200
formula v=d/t
What is average speed?
300
The resulting force
What is net force?
300
If two objects have the same mass and a greater force is applied to one of the objects, the object with the greater_______ will change speeds more quickly.
What is force?
300
A force that always attracts or pulls objects toward each other without direct contact or impact.
What is gravity?
300
Occurs when there is a change in position of an object with respect to a reference starting point.
What is motion?
300
Both the speed of an object and the direction of its motion.
What is velocity?
400
Will cause no change in the speed of an object.
What are Balanced forces?
400
If in a tug of war, one team pulls harder than the other
What is unbalanced force?
400
Force=Mass x Acceleration
What is Newton's Second Law?
400
The location of an object.
What is position?
400
If an object is moving forward, it has ________ velocity
What is positive?
500
When forces act in the same direction, their forces are _________. When forces act in opposite directions, their forces are ________.
What is added and subtracted?
500
Are not equal, and they always cause the motion of an object to change the speed and/or direction that it is moving.
What are unbalanced forces?
500
A force that occurs when one object rubs against another object.
What is friction?
500
A graph used to show a change in an object’s location over time.
What is position-time graphs?
500
Contain a unit of distance divided by a unit of time. Examples of units of speed might include “meters per second” (m/s), “kilometers per hour” (km/h), or “miles per hour” (mph or mi/hr).
