Acceleration is the time rate of change of velocity. If velocity is constant, then acceleration is zero. Note: "100 km per h for 10 seconds" is a constant speed, but not necessarily a constant velocity, since we're told nothing about the direction. If the car moves in a perfectly straight line during those 10 seconds, then its velocity is constant. If it makes a curve, then its velocity is not constant even though its speed is, and there is acceleration.

Acceleration occurs when velocity changes over time. The formula for it is as follows: a = (Vf - Vi) / t a: acceleration (meters/seconds2) Vf: Final velocity (meters/seconds) Vi: Initial Velocity (meters/seconds) t: Time (seconds)

Yes, velocity is acceleration x time. If acceleration is the same, velocity can be different as it changes with time. For example a car accelerating with constant acceleration will have a different velocity after 5 seconds than it will have at 2 seconds.

what is the change in speed or velocity? average acceleration will be change in speed or velocity divided by time taken (4 seconds in ur case)

Acceleration= distance / velocity squared

That depends on its initial velocity and its acceleration. V1 = V0 + a * t

If velocity is steady and doesn't change, then there is 0 acceleration.

Zero. Anything that moves at a steady velocity has no acceleration by definition, because acceleration is defined as rate of change in velocity.

The answer will depend on its acceleration.

The acceleration of the ball can be easily found using the kinematic equation if = vi + at. Where vi = initial velocity, if = final velocity, a = acceleration, and t = seconds. The acceleration is -0.1 m/s^2.

A change in velocity is known as acceleration. Acceleration, in meters per second squared, is equal to velocity, in meters per second, divided by time, in seconds.

To calculate velocity using acceleration, start by multiplying the acceleration by the change in time. For example, if the acceleration is 10 m/s2 and the change in time is 5 seconds, then there is a 50 m/s increase in velocity. Then, add the initial velocity to the increase in velocity.
