The average velocity of an object will equal its instantaneous velocity only when the velocity is increasing at a constant rate. True or false?
Answer)
It is false.
The average velocity of an object will equal its instantaneous velocity only change in speed is zero, but here it is increasing at constant rate.

If an object's instantaneous velocity is constant for some time interval, a plot of its position x versus time t during this time interval will always be a horzontal line. True or false?
True/False: If the average speed of an object is zero, then its average velocity must be zero, but t its average velocity is zero, its average speed is not necessanily zero False An object is dropped from rest into seconds. How much deeper is the second pit, compared to the first pt? a pit, and accelerates due to gravity at roughly 10 m/s2. it hits the ground in 5 seconds A rock is then dropped from rest into a second...

1. When an object is dropped, the motion diagram shows the object having a velocity vector that is increasing in magnitude as a function of time. A. True B. False 2. f one throws a ball straight up, the acceleration of gravity is positive, while dropping or throwing a ball straight down it would be negative. A.True B. False 3.
An object moving in the *x direction experience an acceleration of *2.0 m/s^2- This mean the object is increasing its velocity by 2.0 m/s every second. travels 2.0 m In every second. is traveling at 2.0 m/s. is decreasing its velocity by 2.0 m/s every second. Suppose that an object is moving with a constant velocity. Which statement concerning Its acceleration must be correct? The acceleration is constantly increasing. The acceleration is a constant non-zero value. The acceleration is constantly...
