Are acceleration and force proportional or inversely proportional values?

Yes, acceleration and force are directly proportional to each other.

Explanation:

The force acting on an object is given by :

F = ma

Where

m is mass

a is acceleration

It can be clear from the above formula that the acceleration and the force are directly proportional to each other.

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j

friction

explanation:

they us to move forward and backwards
