This AP Physics 1 quiz checks conservation of energy with 10 multiple-choice questions and instant feedback; every answer comes with a short explanation.

A crate is lifted 3.0 m. Which change would double the gain in its gravitational potential energy? A spring is stretched twice as far. By what factor does its stored energy change? A smooth roller coaster car starts from rest 20 m above the ground. Ignoring friction, which quantity does not affect its speed at ground level? In a bar chart, a block slides down a rough slope. Compared with the top, the bottom state has Which unit is a unit of energy? A 100 W motor and a 400 W motor each lift an identical load by the same height. Which statement is correct? A cyclist rides at constant velocity along a flat road against a 40 N resistive force at 10 m/s. The power delivered by the rider to the bicycle is A student calculates the potential energy of a ball on a hillside using the length of the slope. This is wrong because gravitational potential energy depends on A 0.50 kg ball is thrown straight up at 8.0 m/s. What is its maximum height, ignoring air? A motor with an efficiency of 80 % delivers 2.0 kW of useful power. The input power is Gravitational potential energy formula near Earth? — U = mgh, in joules Elastic potential energy of a spring? — U = ½kx² Kinetic energy formula? — K = ½mv² What does a bar chart check? — That total energy balances between states Energy account with work and friction? — K₁ + U₁ + W = K₂ + U₂ + thermal energy Definition of power? — Rate of energy transfer, P = ΔE/t Power from force and velocity? — P = Fv cosθ Value of one watt? — 1 joule per second One kilowatt-hour in joules? — 3.6 × 10⁶ J Efficiency formula? — Useful output ÷ total input Keep going with Lina
