Answer:
If the velocity and time is given acceleration is calculated by the formula Acceleration = velocity by time
If the Force and mass of an object is given the acceleration is calculated by the formula Acceleration = Force ÷ mass
Step-by-step explanation:
if the object is changing the velocity then the object is accelerating. So Acceleration = Velocity by time
Unit of acceleration = meter per second (m/s) in SI units.
Dividing distance by time is same as dividing distance by the square of time So acceleration = meter per second square (m/s²)
Force (F) is Mass (m) times acceleration (a)
F = ma
so Acceleration = Force ÷ mass
