Episode 216: Energy Changes
This learning episode, from the Institute of Physics, looks at kinetic energy, work and velocity in relation to the braking distance of a vehicle. Two experiments are included, both of which connect work done in braking to the initial kinetic energy of the decelerating vehicle. The activities include: • discussion of work, force and distance to emphasise the link between initial kinetic energy and work done in deceleration • investigating the movement of a sliding block on a surface • student calculations
