Question

When the final velocity is less than the initial velocity, this is speed time acceleration deceleration

Answer 1

The answer is Negative acceleration.

Hope this helps!

Answer 2

Hello!

When the final velocity is less than the initial velocity, this is deceleration

Why?

Acceleration is defined as the physical magnitude that measures the change in velocity with time. The units to express acceleration are speed over time.

The equation for acceleration is:
`a=(v-v_o)/(t-t_o)`

Where: a=acceleration, v=final velocity, vo=initial velocity, t=final time, to=initial time.

If the final velocity is less than the initial velocity, then the acceleration is negative, and that is called deceleration. An example of this is when a car brakes.

Have a nice day!
