Name the forces acting on a plastic bucket containing water held above ground level in your hand.
Discuss why the forces acting on the bucket do not bring a change in its state of motion.
Asked by Topperlearning User | 4th Jun, 2014, 01:23: PM
The forces acting on the plastic bucket are muscular force and gravitational force.
The forces do not bring any change in the state of motion of the bucket because the forces are equal in magnitude but acting in opposite directions. So, the net force on the bucket becomes zero. The effect of the gravitational force will pull it down only if the muscular force gets weaker than the gravitational force when we feel tired.

- define gravitational force
- what is non contact force
- How can we say that force is an interaction between 2 objects if non contact force is also there?
- What do we call such forces that do not require any physical contact with the object on which they act? Give two examples of such forces.
- What is gravitational force? Give two examples from your daily life.
- What happens when two magnets are brought near each other?
- A rocket has been fired upwards to launch a satellite in its orbit. Name the non contact force acting downwards on the rocket immediately after leaving the launching pad.
- Why does an object always fall downwards and not upwards?
