A push or pull.
The strength of a force is measured in the SI unit.
the combination of all forces acting on an object.
A net force acting on an object can make it unbalanced.
equal forces acting on an object in opposite directions.
the force that two surfaces exert each other when they rub together.
friction that acts on objects that are not moving.
friction that occurs when one solid surface slides over another.
friction that occurs when an object rolls over a surface.
friction that occurs as an object moves through a fluid.
the force of attraction between all masses in the universe.
A measure of the amount of matter in an object.
the force of gravity on a person or object at the surface of the planet.
the motion of a falling object when the only force acting on it is gravity.
objects falling through air experiance a type of fluid friction.
the force of air resistence equals the weight of the object.
an object that is thrown
the tendency of an object to resist any change in its motion
a moving object that is to the mass and the velocity of the object.
Law of conservation of momentum
The rule that in the absence of outside forces the total momentum of objects that interact does not change.
any celestial body orbiting around a planet or star
any force that causes an object to move in a circular path.
the force exerted on a surface divided by thue total area which the force is exerted.
a unit of pressure equal to one newton per square meter.
A material that can easily flow.
an instrument that measures atmospheric pressure.
upward force exerted on an object immersed in a fluid.
the buoyant force on an object is equal to the weight of the fluid displaced by the object.
the amount per unit size.
When force is applied to fonfined fliud, the change in pressure is transmitted equally to all parts of the fluid.
