Sliding block model: KE transforms into PE and thermal energy.
This simulation uses a sliding block. Kinetic friction does negative work and converts mechanical energy into thermal energy.
This interactive 3D physics simulation demonstrates the principle of conservation of energy using a block moving up an inclined ramp with friction. It is designed to help students understand the work–energy theorem, including the relationships between kinetic energy, gravitational potential energy, thermal energy, and non-conservative work.
As the block moves upward along the ramp, its initial kinetic energy is gradually converted into gravitational potential energy. At the same time, kinetic friction does negative work on the system, transforming part of the mechanical energy into thermal energy.
The total energy transformation for the motion is described by:
Since the vertical height is related to the distance along the ramp by h = d sin(θ), the stopping distance becomes:
When friction is present, the mechanical energy (KE + PE) decreases as the block moves upward. However, this does not violate energy conservation. The energy lost from mechanical energy appears as thermal energy due to non-conservative work.
The motion begins with kinetic energy determined by the initial speed.
As the block moves upward, its height increases and potential energy grows.
Friction converts mechanical energy into thermal energy.
Total energy remains constant when mechanical and thermal energy are both considered.
