The kinematic equations are often used in a situation in which;1 pointthe aceleration varies with timethe velocity is constantin timethe velocity varies in timethe acceleration is constant in time

When the velocity of a body is variable, then :Its speed may be constantIts acceleration may be constantIts average acceleration may be constantAll of the above

Kinematic equations (aka Equations of uniform motion) can only be used when you have a constant...

The constant acceleration equations can be used when …Select one:a.only when gravitational acceleration is known.b.the acceleration does not change for a given condition.c.the acceleration is varying with respect to time.d.you are unable to remember the general equations for displacement, velocity and acceleration.

When a body is accelerated(i) Its velocity always change(ii) Its speed always changes(iii) Its direction always changes(iv) Its speed may or may not change(i), (ii)(i, iv)(ii), (ii)    (ii), (iii)

What is the definition of acceleration?The change in speedThe change in velocityThe change in velocity divided by the time during which the change occursThe change in velocity multiplied by the time of change
