Question

Q.4.Write three equations of motion, by replacing acceleration (a), with acceleration due to gravity, in them.​

Answer 1

Explanation:

Acceleration due to gravity is the acceleration gained by an object due to gravitational force. Its SI unit is m/s2. It has both magnitude and direction, hence, it’s a vector quantity. Acceleration due to gravity is represented by g. The standard value of g on the surface of the earth at sea level is 9.8 m/s2.
