The force of gravity produces acceleration in all C. freely falling objects and this is known as acceleration due to gravity
Explanation:
A body is said to be in free fall when there is only one force acting on the body: the force of gravity.
Gravity is a force that acts downward, i.e. towards the Earth's centre.
If we are near the Earth's surface, the magnitude of the force of gravity on a body is given by
where:
m is the mass of the body
g is known as the acceleration of gravity , whose value near the Earth's surface is ).
We can apply Newton's second law on an object in free-fall, to find its acceleration. In fact, we have:
where F is the force acting on the body and a is its acceleration.
Solving for the acceleration,
And substituting F,
Therefore, every object in free-fall accelerates at towards the ground.

Answer:
The new period will be reduced by 50%
Explanation:
The period of pendulum is given by;
When the length is decreased by 25%, the new length L₂ is given by;
L₂ = 25/100(L₁)
L₂ = 0.25L₁
Thus, the new period will be reduced by 50%
