The position versus time graph is parabolic.
When it is stationary, or when the velocity is constant. If it is speeding up or slowing down, it has acceleration.
The hands of a clock move at a constant speed, not slowing or speeding up. Therefore, the acceleration is a constant 0 rad/s2
Acceleration means speeding up or slowing down, a change in velocity. Since the velocity was constant, the acceleration was. 0
It's possible, but not necessary, that a particle moving with constant speedhas zero acceleration. In order for acceleration to be zero, it's also necessarythat the particle be moving in a straight line.An object moving with constant speed around a curve has acceleration."Acceleration" does not mean "speeding up".
We all grew up thinking "acceleration" means "speeding up". It doesn't."Acceleration" means the speed or the direction is changing.So if a moving object is speeding up, slowing down, or keeping a constant speedon a path that's curving or bending, then there's acceleration going on.
no because constant acceleration describes and object speeding up at an equal rate wheras constant speed describes an object travelling at the same speed over time. By the way i h8 physics don't ever do it
Yes. "Acceleration" does not mean "speeding up". It means any change in speedor direction of motion. If the body is moving on a curve, even at a constant speed,its direction is changing, so there is acceleration.
Sure. If there is any positive acceleration (in the direction of motion) then the speed is increasing. It doesn't matter whether the acceleration is increasing, decreasing, or staying constant. As long as acceleration (in the direction of motion) remains positive, the thing keeps speeding up.
there is no acceleration if the body is moving with constant velocity

Acceleration is a change in velocity. Assuming a constant direction, if you're speeding up that is positive acceleration. If you are slowing down, that's negative acceleration. Either way you are accelerating.
Increasing speed is acceleration. Some examples include: 1. A car speeding up (accelerating) from a parked position to 30mph. 2. A person speeding up to a walking pace from a sitting position. 3. An airplane speeding up from its runway position to its speed at lift-off.
