Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What causes a falling object to accelerate?
A
weight
B
starting speed
C
direction object is falling
D
gravity
Explanation: 

Detailed explanation-1: -The acceleration due to gravity at or near Earth’s surface is 9.8 m/s2. Gravity is a force that pulls objects down toward the ground. When objects fall to the ground, gravity causes them to accelerate. Acceleration is a change in velocity, and velocity, in turn, is a measure of the speed and direction of motion.

Detailed explanation-2: -When there is a net force on an object, it causes the object to accelerate in the direction of the net force; this is not the same as the direction of the motion unless the object is going in a straight line.
