Question

This investigation can show how which of the following affects the force needed to move an object up an inclined plane?

a) The mass of the object.
b) The height of the inclined plane.
c) The length of the inclined plane.
d) The surface area of the object.

Answer 1

The force needed to move an object up an inclined plane is affected by the mass of the object, the height of the inclined plane, and the length of the inclined plane.

Step-by-step explanation:

The force needed to move an object up an inclined plane is affected by:

1. The mass of the object: Heavier objects require more force to move up the plane compared to lighter objects.
2. The height of the inclined plane: Higher inclines require more force to move the object up compared to lower inclines.
3. The length of the inclined plane: Longer inclined planes require more force to move the object up compared to shorter planes.

Option d) The surface area of the object does not affect the force needed to move an object up an inclined plane.
