a push or pull
the SI unit in which the strength of a force is measured in
the combination of all forces acting on an object
forces that can cause an object to stop moving, start moving or change direction
equal forces acting on an object in opposite directions
What do unbalanced forces acting on an object result in ?
Unbalanced forces acting on an object result in a net force and a change of direction to the direction of the larger force
What do balanced forces acting on an object result in ?
Balanced forces acting on an object do not change the object's motion.
the force that two surfaces excert on each other when they rub against each other
friction that occurs on objects that are not moving
friction that occurs when two solid surfaces slide over each other
occurs when an object rolls across a surface
occurs when a solid object moves through a fluid
the force that pulls objects toward each other
What does the law of universal gravitation state ?
The law of universal gravitaion states that the force of gravity acts between all objects in the universe.
What affects the gravitational force between objects ?
mass and distance
a measure of the amount of matter in an object
the force of gravity on a person or object at the surface of a planet
when the only force acting on a falling object is gravity
Why do objects accelarate toward the center of the Earth?
gravity is unbalanced
a type of fluid friction objects falling through air experience
the highest velocity a falling object can achieve
an object that is thrown
