Question

Horizontal circular motion questions:

1. if net force of an object is constant in magnitude and always directed perpendicular to its velocity, the speed of an object is
a. decreasing
b. increasing
c. zero
d. constant

2. The net force on a vehicle traveling at a constant speed on a curved path points
a. in the direction of motion
b. to the center of curvature
c. opposite the direction of motion
d. away from the center of curvature

Answer 1

1. D, constant
Force must be in the direction of the velocity to change speed.

2. B. to the center of the curvature
This allows the vehicle to complete the turn.
