# how to find acceleration in physics?

##### Matthew Clemens, Physics and Math Teacher, Parent, Tutor, and Professional Ski Instructor

How to find acceleration depends on what you are given. However, the definition of acceleration is the rate of change in velocity or change in velocity/change in time. The formula that describes the conditions and variables that affect how much an object accelerates is known as Newton's 2nd Law which states that acceleration equals Net Force/mass.

Acceleration is a measure of the change in the velocity of an object per unit time and mathematically it is given as accelaration=change in velocity/time If the velocity of an object changes from an initial value u to the final value v in time t, the acceleration a is given by, a=(v−u)t and this kind of motion is called accelerated motion. A body has uniform acceleration if it travels in a straight line and its velocity increases by equal amount in equal intervals of time for example freely falling bodies, motion of ball rolling down the inclined plane etc. A body has non uniform acceleration if its velocity increases or decreases by unequal amount in equal intervals of time. If acceleration is in the direction of the velocity then it is positive acceleration and if it is in the direction opposite to the direction of velocity then it is negative and the negative acceleration is termed retardation. SI unit of acceleration is m/s2.

Acceleration (normally used in equations as a lower case 'a') can be found in many equations in physics.

Most generally, acceleration is equal to the rate of change of velocity, or change in velocity divided by change in time.

Newtons second law describes how Force is equal to Mass x Acceleration (F=ma). You will also see acceleration in other physics equations, such as the acceleration of motion in a circle is equal to velocity squared divided by radius. Hope this helps!
