What will happen if an object is dropped from a height and there is no air resistance?

a

Its acceleration will increase

b

Its speed will increase

c

It will fall with a constant speed and acceleration

d

Both speed and acceleration will increase

Answer : Option B
Explanation :

When an object is dropped from a height and there is no air resistance, the only force on it is the gravitational force.The falling object increases its speed as it falls, because its weight (the force of gravity) pulls it to Earth. It will fall faster until it reaches its terminal speed, which is reached when the upward (air resistance) and downward (weight) forces are equal.
