Answer:
Applied force, weight, normal force and frictional force
Explanation:
Bob is pushing a lawn mower up a hill with the mower tilting slightly to the right. We have to write the forces acting on the mower.
The following are the forces that are acting on the mower.
1. Applied force - The force with which Bob is pushing a lawn.
2. Weight - Its weight is equal to, W = m g
3. Normal force - that balances its weight
4. Frictional force - It always opposes the motion of the mower.
Hence, this is the required solution.
The lawn mower is acted upon by four different forces.
Vector quantities are those quantities that posses both magnitude and direction. Force is a vector quantity. Hence, the resultant force acting on a lawn mover can be obtained as the resultant of the four forces that act on the mower.
The four forces that act on the lawn mower are;
Hence, the lawn mower is acted upon by four different forces.
