experiment explores how energy transforms during free fall,
illustrating the ____
work-energy theorem
a fundamental principle in physics that relates the work done on an object to its change in kinetic energy
work-energy theorem
work done by all forces acting on an object is equal to the change in its kinetic energy
work-energy theorem
formula for work-energy theorem
W(net) = ΔKE = KE(final)− KE(initial)
the energy an object possesses due to its motion; when forces do work on an object, they can change its speed
kinetic energy
TRUE OR FALSE: if no net work is done, the kinetic energy remains constant, meaning the object moves at a steady speed
true
law of conservation of energy
energy cannot be created or destroyed; it can only be transformed from one form to another or transferred between objects, but the total energy remains constant in an isolated system
supports much of classical physics, chemistry, and other sciences as it explains how energy flows and changes in physical processes
law of conservation of energy
tells us that energy is a universal
quantity that stays the same in total, even though it can change forms or move between objects
law of conservation of energy
