What is an example of constant motion?
A ball rolling at a constant speed at the same rate of speed on a still surface.
Can an object be accelerated if it has a constant speed?
Yes. Acceleration means either speed or direction is changing. If direction is changing,then that's acceleration, even if speed is constant.
How is it possible for a car to be accelerating if its speed is a steady 65 mph?
The term accelerating means increasing in speed, so if a car holds its speed steady at 65 mph, it is not accelerating. It is still running its engine, to overcome air resistance and other forms of friction, but that is not the same thing as acceleration.
What is an example of inertia at work?
A car is an example. That is when you stop accelerating ( applying a force) the car still continues on.
How is Acceleration related to speed?
Acceleration is the rate of change of velocity (not speed). Acceleration is the rate of change of velocity over time. Velocity is defined by speed and direction. A satellite orbiting the earth at a constant speed is still accelerating because gravity is making it travel in a circle (or ellipse) and consequently its direction and therefore its velocity is constantly changing.
Can a body have constant speed and still be accelerating give example?
Yes. The simplest example is an object moving at a constant speed in a circle.
When is a time where speed does not change but the object is still accelerating?
Acceleration is the time rate of change of velocity. Velocity is a vector. It has a magnitude ( speed ) and a directio. If either the speed or the direction of motion changes the object is accelerating. Example; an object moving in a circle at constant speed is accelerating because its direction is continually changing.
CAN AN Object accelerate and be moving at a constant speed?
Yes, it's direction may be constantly changing which would mean it is still accelerating.

How can an object have zero acceleration?
i am ten so this will be a wimpy answer. it is an object that has nothing to propel it and therefor it has no acceleration. see wimpy Actually the above is wrong because an object can still be moving but it is accelerating only when there is a change in speed or direction. A car moving at a constant speed of 50 m/h is not accelerating however we can agree that it is still moving.
Can a body have a constant speed and still be accelerating?
Yes, unlike velocity which is a vector and has both magnitude and direction, speed is a scalar and lacks a fixed direction. Therefore you can have constant speed in a circular motion and a centrally directed acceleration which is equal too a=v2/r where v in this case would be speed not velocity. Any body that is constantly changing direction can have constant speed while being accelerated. The change in direction need not by circular, or uniform in any way.
Can you accelerate and keep the same speed?
Acceleration means any change in either speed or direction of motion.If speed remains constant, there may still be acceleration present if thedirection of the motion is changing.If the rate at which speed and/or direction are changing remains constant,then the acceleration is constant

Can a body have a uniform speed having an acceleration?
Yes a body can have both a uniform speed and an acceleration. This is because speed is a scalar quantity, meaning it does not depend on direction. Acceleration is a vector quantity, meaning it does depend on direction. This means that when you are changing direction you are accelerating in that direction. During this time your speed may remain constant. Think about taking a turn in a car. You can put on enough gas to keep you at 20 mph but you are still changing direction so you are accelerating.
