______ is an object's place or location.
|
Position
|
|
|
The motion of an object depends on:
|
1.Your frame of reference
2.On your motion when you observe the object |
|
|
_____ is a measure of the distance an object moves in a given time.
|
Speed
|
|
|
_______ _____ is the total distance divided by the total amount of time
|
Average Speed
|
|
|
If a ball rolls 10 meters in 5 seconds, its average speed will be:
|
2 meters per second because 10 divided by 5 equals 2
(10/5=2) |
|
|
An object's speed in a particular direction is its_______
|
Velocity
|
|
|
For two objects to have the same motion, they must have(or be):
|
1. The same speed
2. Going in the same direction |
|
|
A change in velocity is called___________
|
Acceleration
|
|
|
Slowing down is a type of acceleration called ___________
|
deceleration
|
|
|
The only time you are not accelerating is when:
|
You are moving in a straight line at a constant speed.(or the same speed)
|
|
|
________ is a measure of how hard it is to slow something down.
|
Momentum
|
|
|
The formula for momentum is:
|
Velocity times Mass
(Velocity X Mass) |
|
|
Which object has more momentum?
An object weighing 200pounds with a velocity of 50 kilometers per hour km\hr, or an object weighing 100 pounds with a velocity of 120 kilometers per hour |
B) The object has a momentum of 12,000
|

|
|
If two objects have the same velocity, the one with the greater amount of _____ has more momentum.
|
Mass
|
|
|
A cruise ship is hard to turn because it has a great amount of _______
|
Momentum
|
|
|
A bullet fired from a gun is dangerous because of its _______
|
Velocity
|
|
|
The formula for average speed is:
|
Average Speed equals Total distance divided by total time.(or Average speed= total distance/ total time.)
|
|
|
______ is a change in an object's position.
|
Motion
|
|
|
Momentm is the ________ of an object's velocity and it's mass
|
Product
|
|
|
