Question
The Moon is smaller than Earth and so has less gravity (it has a smaller value for g). If I went to the moon and measured my mass and my weight, how would they be different from my mass and weight on Earth? a) On the Moon, my weight would be less but my mass would be the same. b) On the Moon, my weight would be the same but my mass would be less. 1. 2. A car is parked on a hill. What type of friction keeps it from sliding down the hl? A box is stationary on the floor. It has a mass of 10 kg. Calculate the normal force of the floor on the box. on 3. Another box has a normal force of 200 N acting on it. You start dragging the box across the floor with a horizontal force. The coefficient of kinetic friction between the box and the floor is 0.25. What is the force of friction on the box? 4.Explanation / Answer
1.
mass is a universally constant thing and will not change. hence the mass remain same at both earth and moon
weight = mg
since weight depends on the value of "g" . hence weight will be larger on earth and smaller on moon .
so choice a)
2)
Static friction
3)
Normal force = mg = 10 x 9.8 = 98 N
4.
normal force = 200 N
frictional force = coefficient of friction x normal force = 0.25 x 200 = 50 N
