The formula for calculating acceleration on an inclined plane is a = g * sin(θ), where a is the acceleration, g is the acceleration due to gravity (9.8 m/s^2), and θ is the angle of the incline.
The mass of the block does not directly affect its acceleration on an inclined plane. The acceleration is determined by the angle of the incline and the force of gravity, which is constant.
The angle of the incline has a direct effect on the block's acceleration. As the angle increases, the component of gravity pulling the block down the incline also increases, resulting in a greater acceleration.
No, the acceleration of the block on an inclined plane can never be negative. The block will always experience a positive acceleration due to the force of gravity pulling it down the incline.
Yes, the acceleration of the block on an inclined plane can be affected by friction. If there is friction between the block and the incline, it will act in the opposite direction of the block's movement and decrease its acceleration.
