No, the acceleration of a body as it slides up an inclined plane is not equal to the acceleration as it slides down. The acceleration of the body depends on the direction of motion and the forces acting on it.
When a body slides down an inclined plane, the force of gravity acts in the direction of motion, assisting the body's movement. In this case, the acceleration of the body is greater than zero, and it is given by the formula:
a = g * sin(θ)
Where "a" is the acceleration, "g" is the acceleration due to gravity, and "θ" is the angle of the inclined plane with respect to the horizontal.
On the other hand, when a body slides up an inclined plane, the force of gravity acts in the opposite direction to the motion, acting to slow down or oppose the body's movement. In this case, the acceleration of the body is negative (in the opposite direction of motion) and given by the formula:
a = -g * sin(θ)
The magnitude of the acceleration when sliding up the incline is smaller than when sliding down because it is opposed by the force of gravity.
