Question | Answer |
---|---|
An english scientist and mathematician | Sir Isaac Newton |
Push or pull | Force |
Equal forces acting on one object in opposite directions | balanced forces |
Forces that produce a non zero net force which changes an objects direction | unbalanced forces |
The overall force on an object when all individual forces acting on it are added together | net force |
A unit of measure that equals the force required to accelerate one kilogram of mass a 1 meter per second per second | newton |
The force that two surfaces exert on each other when they rub against each other | friction |
A force that pull things toward each other | gravity |
A measure of the amount of matter in an object | mass |
The force of gravity on a person or object at the surface of a planet | weight |
Objects falling through air experience a type of fluid friction | air resistance |
An object that is thrown | projectile |
The tendency for an object to resist change in motion No | inertia |
An object at rest will stay at rest and an object in motion will remain in motion until acted upon by an outside force | newtons 1st law |
A change in speed or direction depends on an objects mass and overall net force acting on the object | newtons 2nd law |
With every action there is an equal and opposite reaction | newtons 3rd law |
A characteristic of a moving object that is related to the mass and velocity of the object | momentum |
In the absence of outside forces,the total momentum of objects that interact do not change | law of conservation of momentum |
any object that orbits another object in space | satelite |
any force that causes an object to move in a circular path | centripetal force |
