Question

A net force must be acting when an object Choose one or more: A. changes direction but not speed. B. changes both speed and direction. C. accelerates. D. changes speed but not direction.

Answer 1

C. accelerates.

D. changes speed but not direction.

Step-by-step explanation:

• When the body accelerates, the net force increases, when changes speed, acceleration changes and force as well.

`{ \rm{force = mass * acceleration}}`

» So, the force is determined by acceleration.

`{ \rm{force = mass * ( ( \delta \: speed)/(time)) }} \\`

» Also force is determined by change in speed
