100
An object changing in position relative to reference point
What is the meaning of motion
100
Distance / Time = Speed
What formula is used to calculate speed?
100
Final speed - Initial speed / time = acceleration
What formula is used to calculate acceleration?
100
Gravity, Electromagnetic force, strong nuclear force, and the weak nuclear force
What are the four fundamental forces?
100
a quantity whose value does not change
What is the meaning of constant?
200
A force that opposes motion between two surfaces that are in contact
What is the meaning of friction?
200
How fast an object is moving
What does speed tell you?
200
The acceleration that occurs when an object moves in a circular path
What is centripetal acceleration?
200
They act to change the motion of the object
What is similar about the four fundamental forces ?
200
The speed of an object in a particular direction
What is the meaning velocity?
300
The force that opposes the movement of two forces that are in contact and are moving over each other
What is the meaning of kinetic friction?
300
Measure the distance traveled in a shorter time interval
How can you find the speed, when given a point?
300
Negative
When a car slows down so it can stop does it have a positive or negative acceleration?
300
If the forces are balanced, then an object at rest will remain at rest and a object in motion will remain in motion.
How do balanced forces affect an object's motion?
300
A space between objects, units, points, or states
What is the meaning of interval?
400
The force that resists the initiation of sliding motion between two forces that are in contact and at rest
What is the meaning of static friction?
400
Combine the two velocities
How do you find the resultant velocity?
400
At every point in the circle the direction of the object changes, so your are constantly accelerating.
How does an object moving in a circular path accelerates, if the speed of the object doesn't change?
400
Electromagnetic force
Which fundamental force cause friction?
400
The rate at which velocity changes overtime; an object accelerates its speed, direction, or both change.
What is the meaning of acceleration?
500
A system of specifying the precise location of objects in space and time
What is the meaning of frame of reference?
500
The starting point and the ending point
What is used to measure displacement?
500
The acceleration does not change with time
What is constant acceleration?
500
Something that reduces the friction between surfaces. (ex: oil)
What is lubricant?
500
Basic
