a cup of coffee has a mass of .297 kg if you place this cup of coffee on a desk and let it sit there undisturbed how much force is the desk exerting on it
The desk is exerting a normal force of approximately 2.913 Newtons on the cup of coffee, which is also equal to 2.913 N in magnitude.
The force that the desk exerts on the cup of coffee is known as the normal force. This force counteracts the weight of the coffee cup due to gravity. The normal force is equal in magnitude and opposite in direction to the force exerted by the cup's weight.
The weight of an object is given by the equation:
Weight = mass × acceleration due to gravity
Where:
Mass = 0.297 kg (mass of the coffee cup)
Acceleration due to gravity (on the surface of the Earth) ≈ 9.81 m/s²
Weight = 0.297 kg × 9.81 m/s² ≈ 2.913 kg m/s² (Newtons)
