The force that two surfaces exert on each other when they rub against each other is called this.
What is friction?
100
This is a force that pulls objects toward each other.
What is gravity?
100
This law of motion states that an object at rest will remain at rest, and an object moving at a constant velocity will continue moving at a constant velocity, unless is acted upon by an unbalanced force.
What is Newton's First Law of Motion.
100
Any object that orbits another object in space.
What is a satellite?
200
The SI unit used to measure force.
What is Newton?
200
The friction that acts on objects that are not moving is called this.
What is static friction?
200
The measure of the amount of matter in an object.
What is mass?
200
This law of motion states that acceleration depends on the object's mass and on the net force acting on the object.
What is Newton's Second Law of Motion?
200
Any force that causes an object to move in a circular path is called this.
What is centripetal force?
300
The combination of all forces acting on an object at one time.
What is net force?
300
This friction occurs when an object rolls across a surface.
What is rolling friction?
300
The force of gravity on a person or object at the surface of a planet is known as this.
What is weight?
300
This law of motion states that if one object exerts a force on another object, then the second object exerts a force of equal strength in the opposite direction on the first object.
What is Newton's Third Law of Motion?
300
This Law of Motion is displayed every time a rocket lifts off into space.
What is Newton's Third Law of Motion?
400
These forces acting on an object result in a net force and cause a change in the object's motion.
What is unbalanced forces?
400
This friction occurs when two solid surfaces slide over each other.
What is sliding friction?
400
When the only force acting on an object is gravity, the object is said to be in this.
What is free fall?
400
The tendency of an object to resist a change in motion.
What is inertia?
400
This law states that, in the absence of outside forces, the total momentum of objects that interact does not change.
What is the Law of Conservation of Momentum?
500
Equal forces acting on one object in opposite directions are called this.
What is balanced forces?
500
This friction occurs when a solid object moves through a fluid.
What is fluid friction?
500
A type of fluid friction that objects experience when falling through the air.
What is air resistance?
500
A characteristic of a moving object that is related to the mass and the velocity of the object.
