In symbols, average acceleration a− is a−= ΔvΔt=vf−v0tf−t0. The SI unit for acceleration is m/s2 . Acceleration is a vector, and thus has a both a magnitude and direction. Acceleration can be caused by either a change in the magnitude or the direction of the velocity. Instantaneous acceleration a is the acceleration at a specific instant in time. Deceleration is an acceleration with a direction opposite to that of the velocity.

According to this law, a body at rest tends to stay at rest, and a body in motion tends to stay in motion, unless acted on by a net external force.

Projectile Motion: The motion of an object thrown or projected into the air, subject to only the acceleration of gravity. Newton’s Laws of Motion: Three fundamental laws describing the relationship between the motion of an object and the forces acting on it.

If the initial velocity is +15.0 m/s and 5.0 s is required to slow down to +5.0 m/s, what was the car’s acceleration? Average acceleration is the rate of change of velocity, or the change in velocity per unit time. If an automobile slows from +26 m/s to +18 m/s in a period of 4.0 s, what was the average acceleration?

The acceleration due to gravity gives rise to a common (non-SI) unit of acceleration, also called the g :

The SI unit for acceleration is meters per second squared. Acceleration can be caused by a change in the magnitude or the direction of the velocity, or both. Instantaneous acceleration is the slope of the velocity-versus-time graph.

And if you are familiar with basic calculus, it is easy to obtain a general solution for a velocity as the n th degree function of time. From it, we obtain the value of the velocity at that instant of time. The generalization of equation (i) and (iii) is similar to the generalization of (ii).
