Ignore?
inertia
_______ is the property of an object that leads it to resist any change in motion
balanced force
Equal forces acting on an object in opposite directions
forces
Something that does work or causes a change
unbalanced force
force acting on an object that causes a change
Velocity
a speed in a particular direction.
Gravity Definition
The natural force of attraction exerted by anything that has mass, tending to draw them toward the center of the body.
Gravity Formula
g = G * (m1 * m2)/d^2
weight
A force that comes from gravity pulling down on any object with mass
momentum
(p) vector quantity describing the quantity of motion or inertia in motion. Recognizes that both mass and velocity have a part in the motion of an object and is proportional to both (is zero …
Newton's first law
An object at rest remain and an object in motion remains in motion UNLESS it experiences an unbalanced force. Also called the Law of Inertia.
Newton's second law
Acceleration is produced when a force acts on a mass, the greater the mass, the more force is required to accelerate the object.
kinetic energy
a running dog
Potential Energy
(mass) x (g) x (height)
gravitational potential energy
an icicle hanging from a rooftop
Power
(physics) the rate of doing work
mass
a body of coherent matter, usually of indefinite shape and often of considerable size
net force
Acceleration depends on the
acceleration
(physics) a rate of change of velocity
Newton (N)
SI unit Force
action
the force one object applies to another
Force Pairs
the action-and-reaction pair of forces that constitute an interaction (collision)
reaction
A response to a stimulus.
collision
A situation in which two objects in close contact exchange energy and momentum
