Question

Objective Type Questions:
1. Mass of an object is 12 kg. Its weight on the moon will be
19.6 N
b. 29.6 N c. 84.4 N
d. 96.2 N
2. The work done on an object does not depend upon the
a. displacement b. force applied c. angle between force and displacement d. initial
velocity of the object.​

Answer 1

Answer:

1. a. 19.6N

2. d. initial velocity of the object

Explanation:

1. Acceleration due to gravity on moon=1/6 * Acc. due to gravity on earth.

Hence, weight on moon= (12*9.8)/6 N

= 19.6 N

2. Work can be defined as the dot product of Force and displacement i.e, W= Force*displacement* cos (theta),

where, theta= angle between force and displacement.
