The essentials of a lesson, in one place

Newton’s second law connects the net force on an object, its mass and its acceleration.

F = m × a

At constant mass, a greater net force produces greater acceleration.

Example from a physics lesson

Why does the block accelerate?

The net force equals m × a. With the same mass, a larger net force means greater acceleration.

What if the mass doubles?

With the same net force, acceleration is halved. You can check this using a = F ÷ m.
