Question

Which of the following experiences balanced force- a. ball dropping vertically. b. car accelerating uniformly from rest. c. a trolley moving at a constant velocity down a slope. d. a plane flying in a circle with constant speed.

Answer 1

Answer:

When there is an increase the steepness of the slope, there will be an increase the speed of a ball rolling down the ramp. This is observed as, the force of gravity points straight down, but a ball rolling down a ramp does not go straight down, it follows the ramp.
