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.
Answers
Weight of water (contained in it) down wards.
weight of bucket down wards
Pulling (upwards) force due to the hands of the person, directed upwards.
The force exerted by the person = weight of bucket + weight of water
since the three forces are balanced, the net force is zero on the bucket. Hence, the bucket does not move and is in static equilibrium. or state of static inertia.
This is as per the first law of motion of Newton.
The forces acting on the plastic bucket containing water held above ground level in your hand are:
- Gravitational force
- Muscular force
Gravitational force: Gravitational force is force which is applied by Earth's gravity. The object is pulled along the earth because of gravitational force. In simple terms, Gravitational force is the the force between two objects with mass.
Muscular force: The force applied by muscles is called as Muscular force. This force is applied by the body parts like Arm, Leg, Hands etc..
Why the forces acting on the bucket do not bring a change in its state of motion ?
This is because, they are balanced or they have net force of 0. Because of which, The forces acting on the bucket do not bring a change in it's state of motion.
Also, muscular force acts upward direction and gravitational force acts downward. Hence, net force will be 0
