Question

Karthik is observing the live telecast
of a one day cricket match. He noticed
motion of a roller on the pitch during
lunch break. He thought about various
forces acting on the roller and the net
force when it is in motion. Many
questions arose in his mind regarding
the direction of the net force. Can you
guess what would be those
questions?

SCERT Class 8 Telangana, Physical Science Chapter 1 Force

Answer 1

What would be the direction of net force?
How many forces are acting on it?
In which direction are the forces acting on it?
How to calculate the net force acting on it ? If the roller is travelling at a particular speed how much time would it take to move around the ground once? etc

Hope it helps!!!
