Anything that moves with or against gravity
Anything that moves other than with or against the force of gravity
_______ is the property of an object that leads it to resist any change in motion
A man from Italy who first proposed the law of inertia as well as making observations on the Moon, sun, Venus, and jupiter
Units: cm/s, m/s, mi/hr, km/s ...
Distance traveled divided by the time required to cover the distance
Magnitude of instantaneous velocity
a speed in a particular direction.
9.8m/s per second is a
(interactions between two objects)
A change in position (delta p).
A _______ is a place or object used for comparison to determine if something is in motion.
a measure of magnitude
The Pythagorean Theorem
a^2 + b^2 = c^2
1 N = how many lbs?
1 lb = how many Newtons?
A man from England who realized that the planets move around the Sun because of inertia as well as developing the laws of motion and gravity
Free body diagram
A diagram that shows all forces acting on an object, with proper relative magnitudes and directions for objects
∑F = 0
The Equilibrium Rule:
The force that acts against the surface that an object rests on (does NOT always counteract weight)
A state of motion where an object is moving with constant velocity
A state of motion where an object is at rest
An effect whereby a mass moving in a rotating system experiences a force acting perpendicular to the direction of motion and to the axis of rotation
A pendulum whose swing plane changes accordingly throughout the day to the direction of the earth's rotation
Newton's First Law of Motion
An object in motion will stay in motion forever unless it is acted on by an unbalanced force and an object at rest will stay at rest unless an unbalanced force acts upon it as well.
The state of an object or system of objects for which there are no changes in motion. In accord with Newton's first law, if at rest, the state of rest persists. If moving, motion continues without change.
For any object or system of objects in equilibrium, the sum of the forces acting equals zero. In equation form, EF=0.
