Question

Select the correct answer. A car is moving at a constant speed along a straight line. Which statement is true about the forces acting on the car? A. The net force acting on the car from all directions is zero. B. The net force acting on the car is greater than the car's weight. C. The net force acting on the car is in the direction of the car's motion. D. The net force acting on the car is in the opposite direction of the car's motion.

Answer 1

A

Step-by-step explanation:

For an object to move with constant speed the forward force is opposed by the effects of forces. There is no resultant force acting or constant speed is a result of no resultant force.

Newton's second law states that an object with no net forces acting on it which is initially at rest will remain at rest. If it is moving, it will continue to move in a straight line with constant velocity. Newton's Second Law states: F = ma. F is the net force acting on an object.

Also if velocity or speed is constant the acceleration will be 0 the F=m×0

F=0.
