Answer to Question #106689 in Physics for pooya

Question

1. (5 points) Choose all of the following statements that are correct about Newton’s laws of motion:
a. If the net force on an object is zero, the object’s velocity is zero.
b. An object with a small mass is easier to decelerate than an object with a large mass.
c. As net force on an object increases, its acceleration increases if its mass remains constant.
d. Newton’s first law states that in the absence of a force, an object either remains at rest or moves with a constant velocity in a straight line.
e. An object moving at a constant velocity must have no forces acting on it.

Answer 1

a. If the net force on an object is zero, the object’s velocity is constant.

e. An object moving at a constant velocity can have forces acting on it. But the net force on an object is zero.

Answer:

b. An object with a small mass is easier to decelerate than an object with a large mass.

c. As net force on an object increases, its acceleration increases if its mass remains constant.

d. Newton’s first law states that in the absence of a force, an object either remains at rest or moves with a constant velocity in a straight line.
