Question

1) A truck starts from rest on a plane road. What
are the possible energy changes taking place
while the truck is in motion ?​

Answer 1

Possible energy changes when a truck starts on a plane road.

• So, initially the truck was at rest. And since we are considering the road to be the reference plane , we can say: Both Potential And Kinetic Energy were zero.

• Now, the truck started to move.

• The energy supplied by the engine of the truck is used to raise the kinetic energy of the truck.

• However, since the truck is still going on a non-inclined plane road, the potential energy will still be zero.

• But, a part of the energy provided by the engine will be converted into heat energy due to friction between the tyres and the road.
