When it is stationary, or when the velocity is constant. If it is speeding up or slowing down, it has acceleration.
A line angled upward
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 is the rate of change of velocity. It can be positive (speeding up), negative (slowing down), or zero (constant speed). Velocity is the rate of change of an object's position with respect to time.
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.
The acceleration of the body was zero during this interval because its velocity was constant. Acceleration is the rate of change of velocity, so if the velocity does not change, the acceleration is zero.
Yes, it is possible for a particle to have constant speed and zero acceleration. If the particle is moving at a constant speed, it means that its velocity is not changing. Acceleration is the rate of change of velocity, so if the velocity is constant, the acceleration must be zero.
No, an object cannot accelerate and have a constant speed at the same time. Acceleration is a change in velocity, which includes speed or direction. If an object has a constant speed, it means there is no acceleration occurring.
Acceleration is the rate of change of velocity with respect to time. Acceleration can be positive (speeding up), negative (slowing down), or zero (constant velocity). Acceleration is a vector quantity, meaning it has both magnitude and direction.

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.
