Which of the following is a condition for work to be done?
No displacement
Force is zero
Displacement in the direction of force
Force applied at an angle of 90 degrees
What is the formula for kinetic energy?
KE = (1/2)mv^2
KE = F × s
KE = mgh
KE = mv
What does potential energy depend on?
Speed of the object
Mass and height
Force applied
Time taken
What is the work-energy theorem?
Work done is equal to energy consumed
Work done is equal to force times distance
Work done is equal to change in kinetic energy
Work done is equal to change in potential energy
What is the formula for gravitational potential energy?
PE = F × d
PE = mv^2
PE = mgh
PE = (1/2)kx^2
What is the SI unit of energy?
Joule
Newton
Watt
Kilowatt
What is the definition of power?
Force applied over distance
Rate of doing work
Energy consumed over time
Work done per unit mass
How is power calculated in terms of work?
P = W × t
P = W / t
P = W + t
P = W - t
What is the relationship between kinetic energy and momentum?
K.E = 2mP
K.E = P / 2m
K.E = P^2 / 2m
K.E = mP^2
