Froggy Jumps Kinetic & Potential Energy QuizVersion en ligne Energy types and basics par Ronamae Olmos 1 What is the formula for kinetic energy? a KE = 1/2 m v^2 b E = mc^2 c PE = mgh 2 What does potential energy depend on in gravity? a Speed of the object b Time spent moving c Height above the reference point 3 Which factor increases gravitational potential energy? a Increasing surface area b Increasing speed c Increasing height while mass stays the same 4 Kinetic energy increases when an object's: a Mass decreases b Speed increases c Height increases 5 If mass doubles and speed stays the same, kinetic energy: a Halves b Remains the same c Doubles 6 Which statement describes energy conservation? a Kinetic energy always decreases b Energy is created when moving c Total mechanical energy can remain constant in ideal conditions 7 What is the unit of kinetic energy in SI units? a Newton (N) b Watt (W) c Joule (J) 8 When an object is at the lowest height in a swing, its potential energy is typically: a Zero only if stationary b Maximum c Minimal 9 An object at height h has 20 J of PE. If height doubles and mass stays same, PE becomes: a 40 J b 10 J c 80 J 10 If velocity doubles, kinetic energy changes by a factor of: a Four times b Two times c Eight times
