If an object has a constant acceleration, the velocity of the object must:*be zerobe constantcontinually change by the same amount each secondcontinually change by varying amounts each second

It is impossible for an object to have:constant speed and constant velocityconstant speed and changing velocitychanging speed and constant velocitychanging speed and changing velocity

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

heck up only the correct statement in the following.A body has a constant velocity and still it can have a varying speedA body has a constant speed but it can have a varying velocity.A body having constant speed cannot have any acceleration.None of these.

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.

What happens to the acceleration of a falling object as it speeds up?2 marksIt remains constantIt decreasesIt increasesIt becomes zero
