B. 10,400 N D. 399 N. C___ 2. If a car is moving to the left with constant velocity, one can conclude that. A. there must be no forces applied to the car. B. the net force applied to the car is directed to the left. C. the net force applied to the car is zero. D. there is exactly one force applied to the car. A___ 3.
If the direction of acceleration is in the same direction as that of velocity then the object is said to be speeding up or accelerating. If the acceleration and velocity are in opposite directions then the object is said to be slowing down or decelerating. An example of constant acceleration is the effect of the gravity of earth on an object in free fall.
