Question

difine the themes (a) acceleration (b) displacement​

Answer 1

a) In mechanics, acceleration is the rate of change of the velocity of an object with respect to time. Accelerations are vector quantities (in that they have magnitude and direction). The orientation of an object's acceleration is given by the orientation of the net force acting on that object

b)Displacement is defined as the change in position of an object. ... It is represented as an arrow that points from the starting position to the final position. For example- If an object moves from A position to B, then the object's position changes. This change in position of an object is known as Displacement
