Question

What is acceleration

Answer 1

Explanation: Acceleration is the rate of change in velocity. Involves a change in speed and direction. When acceleration involves a change in speed only: Positive acceleration it occurs when an object speeds up. Negative acceleration it occurs when an object slows down. Acceleration is a change of velocity over a period of time, expressed by the equation below.

A=Δv/t

vf-vi=Δv/t

A=m/s-m/s/s

=m/s/s=m/s²

m/s/s

Hope this helps!

Thanks!

Have a great day!

Answer 2

Acceleration is a change in motion ... slowing down, speeding up,
or changing direction even if speed doesn't change.
