When the force changes, acceleration changes too, but the magnitude of its change depends on the mass of an object.

This is not true in a situation when the mass also changes, e.g., in rocket thrust, where burnt propellants exit from the rocket's nozzle.

If you've ever wondered what the physics behind space travel are, look at this Tsiolkovsky rocket equation.

We can measure acceleration experienced by an object directly with an accelerometer.

What's more, from the general theory of relativity we know that the entire Universe is not only expanding, but it is even an accelerated expansion!

That means that the distance between two points is constantly becoming greater and greater, but we can't feel that on an everyday basis because every scale in the world expands too.Acceleration is the rate of change of an objects speed; in other words, it's how fast velocity changes.According to Newton's second law, acceleration is directly proportional to the summation of all forces that act on an object and inversely proportional to its mass.You can find there: Acceleration always occurs whenever there is a non-zero net force acting on an object.You can feel it in an elevator when you become a little heavier (accelerating) or lighter (decelerating), or when you're riding down a steep slope on your sled in the snow.It's all common sense - if several different forces are pushing an object, you need to work out what they add up to (they may be working in different directions), and then divide the resulting net force by your object's mass.This acceleration definition says that acceleration and force are, in fact, the same thing.You can derive them from the equations we listed above.All you need to know is that speed is expressed in feet per second (imperial/US system) or in meters per second (SI system) and time in seconds.If you want to switch between different units of mass, here's our weight converter.Both calculators allow you to perform calculations quickly with any set of units you want. If you already know how to calculate acceleration let's focus on the units of acceleration.
