Motion
100
More force equals more _____________.
motion
100
________________ acts in the opposite direction of the object's motion.
Friction
100
Where is one place where friction is non-existent or a minor force?
The moon
200
Decreasing in speed
200
A force that pulls everything towards the center of Earth without touching it.
Gravity
200
The direction in which the force is applied determines the __________ of motion.
direction
200
This is a contact force such as rubbing two objects together and often produces it
friction
200
What is an example of when friction is a good thing?
Playing basketball or tennis court when playing a game
300
Constant speed, Stops completely, constant speed
300
A push or pull
force
300
The _________ of an object describes how much matter it contains.
mass
300
Particles of air bump against the surface of an object causing friction
air resistance
300
What is one way to reduce frictional forces?
Grease or oil inside of machinery.
400
From 0-5 minutes describe what happens.
Constant speed
400
A force which causes an object to remain in place.
Balanced force
400
If a soccer and bowling ball are each kicked with the same amount of force, which ball will move much farther and why?
soccer ball
400
Direction of a force, mass of the object, and ________________________ affect the motion of an object.
strength of the force
400
If you roll a toy car down a steep incline and it doesn't roll very far, what is one way to increase the forward movement of the car?
Add mass to the car
500
Describe the motion of this graph from 5-10 seconds.
stops completely
500
A force can cause an object to start moving, stop moving, or change direction
Unbalanced force
500
Objects fall because the Earth exerts a force on them. This force is called the __________________ force.
gravitational
500
If Frick applies twice as much force in a forward movement toward Frack, which direction does the car move?
toward Frack
500
Excluding air resistance and friction, objects, regardless of mass, fall towards the Earth at the _________ rate of acceleration.
same
