A10kgBoxIsRestingOnAFrictionlessTable,DetermineTheWeightForceAndNormalForceOnTheBox

Question

physics question using free body diagram and labeling arrows with the forces asked to calculate 

Answer 1

Given:

Mass (m) = 10 kg

Gravity (g) = 9.8 m/s²

Table is frictionless, so no friction force.

Box is at rest, so net force = 0.1. Weight Force (W):

This is the force due to gravity pulling down.W = m _ g

W = 10 kg _ 9.8 m/s²

W = 98 N downwards2. Normal Force (N):

This is the force exerted by the table pushing up. Since the box is at rest vertically,

Normal Force balances Weight.N = W

N = 98 N upwardsSo, Weight = 98 N down, Normal = 98 N up.
