Class 11 Gravitation Notes
Acceleration due to gravity (or acceleration of gravity) or gravity acceleration is the acceleration caused by the gravitational force of attraction of large bodies. As we know that the term acceleration is defined as the rate of change of velocity with respect to a given time. Scientists like Sir Isaac Newton and Lord Henry Cavendish soon discovered that this increase in speed, or acceleration, was caused by a different force known as gravity by studying objects falling to the Earth in a variety of circumstances. According to definitions, gravity is a force that pulls objects toward the center of mass , like the Earth. Conversely, acceleration describes how an object’s velocity or speed changes over time. Hence, the value of acceleration due to gravity is 9.8 m/s 2 on earth. What is Acceleration due to Gravity? Acceleration due to Gravity is defined as the acceleration attained by an object due to the gravitational force of attraction. When a body is...
