Momentum and Forces
Vocab about forces, net force, and more.
Terms in this set (22)
the product of a body's mass and its velocity [p=mv]
the tendency of an object to maintain its state of rest or constant motion unless acted upon by an external force
the speed of an object in a particular direction
the rate at which velocity changes.
an object's speed during a particular instant of time
the distance an object travels divided by the time it takes to cover that distance
a push or a pull
the combination of all the forces acting upon an object
two or more forces cancelling each other out, not causing a change in motion
two or more forces which do not cancel each other, but cause a change in motion
Newton's first law of motion
"if an object's net force is zero, the object stays at rest, or if it is already moving, it continues moving with constant speed."
Newton's second law of motion
"an object acted upon will accelerate in the direction of the force"; (acceleration = net force / mass)
Newton's third law of motion
"for every action, there is an equal but opposite reaction"
the rubbing force that acts against motion between two touching surfaces
an object's gravitational force
center of mass
the point in an object that moves if all the object's mass was concentrated at that point
the friction that prevents a static object from moving when a force is applied to it
friction that occurs when one solid surface slides over another.
friction that occurs when an object rolls over a surface
the outward force from a surface
9.8 meters per second squared
the force of gravity
occurs when the force drag (air resistance) is equal to the force of gravity
