What two things do you need to know to solve for the speed of an object?

distance and time

100
The less mass an object has, the less of this is needed to move it.
What is force?
100
A force that that pulls objects to the center of the earth.
What is gravity?
100
An example of this force can be observed during a kickball game when the ball is pitched, but the force between the ball and the ground makes the ball stop before reaching the kicker.
What is friction?
100

When the speed/graph line is curved going up. What is happening?

The speed is accelerating.

200

What part of a speed problem goes in the inside of the Division Bar?

Distance

200
An object in motion will stay in motion, and an object at rest will stay at rest, unless acted upon by an ____________ force.
What is unbalanced?
200
When two objects rub together, they create this force.
What is friction?
200

What item will go the furthest?

A empty card pushed by one person

A empty cart pushed by two people

A full cart pushed by two people

Empty cart by two people

200
The Y axis represents this on a line graph.
What distance?
300
The best way to change the speed and number of cycles of our pendulum.
What is adjust the length of the string?
300

For every action there is an equal and opposite reaction. True or False

True

300
A moving object will do this when friction is increased.
What is slow down or stop?
300

What is the speed of an object going a distance of 200 feet in 10 seconds?

20 feet per second

300
The X axis represents this on a line graph.
What is time?
400
To find this use the formula distance/time (d divided by t)
What is speed?
400
If equal forces are balanced on an object, then this will happen with the object.
What is NO movement?
400
This is the result when weight is added to a vehicle and the force is not increased.
What is slow down or reduce speed?
400
Two objects of different masses are dropped from the same altitude at the same time. They will hit the ground in this order.
What is at the same time?
400
When you have a straight line that is angled up it means this?
What is an object accelerating at a constant or steady speed?
500
In order to start something moving, this must be applied to the object.
What is an unbalanced force?
500
For every action, there is an _____________ and ___________ reaction.
What is equal and opposite
500

What would cause more friction for a car?


Driving on the road

Driving in the woods on the dirt

Driving on the beach

Driving on the beach

500
An object has traveled 420 miles in 7 hours. This is the average rate of speed the object is traveling.
What is 60 miles per hour?
500

This describes the motion of an object's speed if the graph shows a horizontal straight line.

The object is not moving.
