Sci 206: Motion part#1 || CORRECTLY SOLVED!!
define Inertia correct answers a body in motion tends to remain in motion; a body in rest tends to
remain at rest
Define velocity correct answers 1. how fast you are going (speed)
2. which way you are going (direction)
Define acceleration correct answers How fast your velocity is changing
(speeding up, slowing down , changing direction)
Newton's First law correct answers His first law states that every object will remain at rest or in
uniform motion in a straight line unless compelled to change its state by the action of an external
force. (basically the definition of inertia)
Newton's Second Law of motion correct answers the force exerted on an object is equal to the
product of the object's mass times its acceleration. the acceleration is in the same direction of the
force, (f=ma)
** easier to move a light object than a heavy one
Newton's third law correct answers Every action has an equal and opposite reaction
Gravity correct answers Need to consider all the forces acting on the body normal face from
ground
F(gravity) = N-F=0
N= normal force
Equation for force correct answers Force = Mass x Acceleration of gravity (F=ma)
Types of energy (2 types) correct answers 1. kinetic (moving energy)
2. potential (stored energy)
** higher objects have more potential energy
** faster moving objects have more kinetic energy
Define energy correct answers The ability to do work or cause change. it also is converted from
potential to kinetic energy
Define work correct answers the transfer of energy that occurs when a force makes an object
move.
** if you are not pushing or it is not moving then you are not using work
Work equation correct answers force x distance(Fd)
