1. Average speed is a measure of the distance traveled in a certain period of time. Instantaneous speed is is speed at a particular instant in time. Your speedometer shows your instantaneous speed.
2. Constant speed is traveling the same speed over a period of time. 300m
3.A vector quantity that is defined as the rate an object changes velocity. Average Acceleration = deltVelocity / Time = Vfinal - Vinitial / Time. m/s/s, km/h/s, and mi/h/s. 28m/s.
4. Slope = Velocity. As the steeper the slope the higher the velocity, if the slope is curved there is acceleration.
5. They are traveling at 3m/s in a negative direction. Velocity = Df - Di / Tf - Ti
They are traveling at 4m/s Velocity = Df - Di / Tf - Ti
6. The slope = the Acceleration. I the line is going up and to the right it is accelerating if it is going down and to the right it is decelerating.
A), D), H)
7. An object falling under the sole influence of gravity. 9.8m/s/s
8. The object is accelerating. the acceleration of an object on mars is 3.78m/s/s. a= deltaV/ deltat = Vf - Vi / tf - ti = 7.55m/s - 3.77m/s / 2.00s / 1.00s = 3.78m/s/s
