Speed Equation
d/t=m/s
Velocity(def)
displacement traveled per unit of time
Distance in a specific direction
How are speed and velocity different?
Velocity must include a direction
Average Speed
=total distance/total time of travel
Instantaneous Speed
how fast something is moving right now. speedometer speed
Acceleration Equation
a=Vf-Vi/t
(finial-Initial)
Acceleration (def)
rate of change of velocity; not how much faster the speed is but how quickly it changes
What is acceleration measured in?
m/s^2
Negative Value
means decreasing
Newton’s 1st law of motion
Law of Inertia; object at rest will stay at rest, object in motion will stay in motion, unless acted upon by an outside force
Inertia
is resistance to change in motion
Galileo Contribution
Galileo first proposed the idea of inertia with the idea of rolling a ball down one ramp and up another
ramp of varying angles, the ball would always return to the same height
Newton’s 2nd Law of motion
Force
Force Equation
F=ma
Force measured in?
Newtons
Force and acceleration are?
Directional
Newton’s 3rd Law of Motion
For every force there is an equal and opposite reaction force
Forces always come in?
Pairs
balanced forces must both be acting on?
the same object and since they have opposite directions their sum will be zero.
The motion of an object will depend on the?
mass
Speed (def)
Distance traveled per unit of time
