What is the net force?
100
The formula for finding speed.
What is S=d/t?
200
A location that you compare to another location
What is a reference point?
200
A force that resists motion between two surfaces that are pressed together.
What is friction?
200
A force of size or strength.
What is magnitude?
200
The only type of force that can cause motion.
What is an unbalanced force?
200
The equation used to find velocity.
What is V=d/t?
300
The change of position over time.
What is motion?
300
When one object pushes or pulls another object by touching it.
What is a contact force?
300
The acceleration of an object increases with increased force and decreases with increased mass.
What is Newton's Second Law?
300
The law that states that objects remain at rest remain at rest and an object that is in motion stays in motion.
What is Newton's First Law?
300
The resistance of an object to a change in the speed or the direction of its motion.
What is inertia?
400
A graph that plots the distance the object has traveled against time.
What is a distance-time graph?
400
A force that has both size and direction.
What is a vector?
400
A measure of mass in motion; the _____ of an object is the product of its mass and its velocity.
What is momentum?
400
The type of force that can't change the motion of an object.
What is a balanced force?
400
Inertia is the main reason why this must be worn in a car.
What is a seat belt?
500
The measure of how fast something moves in a given amount of time.
What is speed?
500
Friction and gravity affect the ____ and ____ of an object.
What are speed and direction?
500
Every time one object exerts a force on another object, the second object exerts a force that is equal in size and opposite in direction back on the first object.
