Explanation:

Hello!

For an object sliding down an inclined plane, there are two forces working on the object: The normal force and the force due to gravity.

Breaking the force due to gravity into its components, we get a force of:

Mgsinθ, parallel to the incline's slope. This is the NET force acting on the object, causing it to accelerate.

Since ∑F = m · a:

Mgsinθ = m · a

Divide by the mass:

a = gsinθ
