Choices: True or False.

If velocity is zero then acceleration must be zero too.

If speed is constant then acceleration is zero.

If velocity is constant then speed must be constant too.

If speed changes then velocity must change too.

Object slows down if it's acceleration is negative.

If speed is constant then velocity must be constant too.

Force, speed , acceleration and momentum
Sometimes it is convenient to construct a system of units so that all quantities can be expressed in terms of only one physical quantity. In one such system, dimensions of different quantities are given in terms of a quantity X as follows:[position] = [𝑋𝛼]; [speed] = [𝑋𝛽]; [acceleration] =[𝑋𝑝]; [linear momentum] = [𝑋𝑞]; [force] = [𝑋𝑟].
