Acceleration of an object moving along a straight line
The rate at which the velocity of an object changes is called the acceleration of the object. In other words, acceleration is the change in velocity per unit time.
Consider an object moving along a straight path in the same direction. Its velocity changes in a short time period ‘t’. Its velocity at the beginning of the time interval is ‘u’ (initial velocity). Its velocity after time ‘t’ is v (Final velocity).
Acceleration is change in velocity per unit time;
where a is the acceleration produced in the body.
The SI unit of acceleration is . It is a vector quantity.
The acceleration is positive, if it is in the direction of velocity.
The acceleration is negative, if it is opposite to the direction of velocity.
The acceleration is zero, if the object is moving with constant velocity.
