Question

what happens to the average speed of an object if the angle of inclination of the plane is changed???

Answer 1

If angle increase average speed also increase and vise versa

Answer 2

• If the angle of inclination of the plane increases,

   the component of force parallel to the incline (F =mg Sin α )  increases

           α increasing ----> Sin α increasing ----> mg Sin α increasing

By using Newton's second law, F =ma

         F increasing -----> ma increasing------m is a constant------> a increasing

As the angle is increased, the acceleration of the object is increased.

But we know that acceleration is the rate of change of velocity. Therefore,

        a increasing ------> V increasing

Velocity is increased with the angle.
