The motion of a freely falling body is an example of uniformly accelerated motion.
Uniformly Accelerated Motion:
Uniformly accelerated motion refers to the motion of an object where the acceleration remains constant throughout the motion. In other words, the object's velocity changes by the same amount in equal intervals of time.
Freely Falling Body:
When an object is dropped from a certain height and falls freely due to the force of gravity, its motion is known as free fall. In the absence of any other forces (such as air resistance), the only force acting on the object is gravity.
Explanation:
When a body falls freely, it experiences a constant acceleration due to gravity. On the surface of the Earth, the acceleration due to gravity is approximately 9.8 m/s². This means that every second, the velocity of the falling body increases by 9.8 m/s.
During the entire downward motion, the acceleration remains constant. This is because the force of gravity acting on the object is constant, and according to Newton's second law of motion, the acceleration is directly proportional to the net force acting on an object.
Key points:
- The motion of a freely falling body is an example of uniformly accelerated motion.
- The acceleration of a freely falling body is constant and is equal to the acceleration due to gravity (9.8 m/s² on the surface of the Earth).
- The velocity of the falling body increases by 9.8 m/s every second.
- The motion is uniform because the acceleration remains constant throughout the motion.
In conclusion, the motion of a freely falling body is an example of uniformly accelerated motion because the acceleration remains constant during the entire downward motion.
