Question

To investigate changes in the velocity of a body under the action of a constant force and to determine its acceleration

Answer 1

The acceleration can be defined as the rate of change of velocity of a body.

Explanation:

• Let us consider the velocity of the object of mass m to be v

• According to the law of Newton and the other laws of kinematics the acceleration is equal to dv/dt.

• Here t represents the time taken for the particular change in velocity.

• The force is the product of the mass and the acceleration of the body. hence the force that takes place in the body is equal to mdv/dt.

• Here the force is said to be the resultant of all the forces that take place in the body since force is a vector quantity
