Science Physics Newton's Laws of motion
Terms in this set (12)
Newton's First law
A body not acted upon by an external force moves with a constant velocity or is at rest. (Inertia-->resistance of a body to a change in motion).
Newton's second law
Force = mass * acceleration
Newton's third law
Every action has an equal and opposite reaction.
When kicking a soccer ball, if you kick with more force, the soccer ball will experience a _______________ (greater/lesser) acceleration.
A larger soccer ball kicked with the same force will have (less/more) acceleration.
True, every action has an equal and opposite reaction
True or false: when you kick the soccer ball, the soccer ball also exerts a force on your foot.
A measure of the force of gravity on an object
the amount of matter in an object
an object that has been subjected to an _________________ force will speed up, slow down, or change direction.
unit of weight in the metric system
in Newton's second law, given a particular force, mass is _______________ proportional to acceleration.
less (about 1/6 as much)
