a push or pull that acts on an object.
What is force?
100
A strength of measure in units.
What is newton (N)?
100
Pulls objects toward the Earth's center without touching them.
What is gravity?
100
ANY change in motion.
What does the word acceleration in science mean?
100
The total of all forces acting on a body.
What is net force?
200
A force that requires two pieces of matter to touch.
What is contact force?
200
Make an object speed up, slow down, or, change direction.
What can a force do?
200
Acts between objects that are electrically charged.
What is electric force?
200
The motion does not change.
What is Uniform motion?
200
an area of partial darkness where light has been blocked by an object.
What is a shadow?
300
Force that results when two materials rub against each other or when their contact prevents sliding.
What is friction?
300
Depends on their texture, shape, speed, and weight. Also whether the surface is wet or not.
What the amount of friction between two objects may do?
300
A north pole and a south pole.
What does every magnet have?
300
Force = Mass x Acceleration. (F = m x a)
What is the formula that describes the relationship between force, mass and acceleration?
300
Two forces of equal strength that combine to act on the same object but in opposite directions.
What is balanced?
400
A force that acts at a distance.
What is non-contact force?
400
Two things need to touch.
What is for friction to work?
400
The tendency of an object to resist any change in motion.
What is inertia?
400
An object will stay in uniform motion unless a net force acts on the object.
What is Newton's First Law of Motion?
400
to have one force without an equal and opposite force.
What is impossible?
500
The rate at which the speed or direction of motion of an object changes over time.
What is acceleration?
500
Gravity, electric force, and magnetic forces.
What are three examples of non-contact forces?
500
The rate at which the speed or direction of motion of an object changes over time.
What is acceleration?
500
How your body moves in a car when it either stops quickly or turns a corner.
What is an example of inertia?
500
One object exerts a force on a second object, the second object exerts a force on the first.
