Total questions: 10
Worksheet time: 5mins
If an object has a mass of 5 kg and a velocity of 10 m/s, what is its kinetic energy?
100 J
250 J
500 J
250 N
What is the formula to calculate potential energy?
PE = 1/2kx^2
PE = mgh
PE = 1/2mv^2
PE = Fd
If an object has a mass of 2 kg and a height of 4 m, what is its potential energy?
The potential energy is 100.8 Joules
The potential energy is 78.4 Joules
The potential energy is 50.2 Joules
The potential energy is 10.5 Joules
If a work of 100 J is done to move an object a distance of 5 m, what is the Force done?
20 J
20 N
200 J
20 m
What are the units for work?
newtons (N)
kilograms (kg)
meters (m)
joules (J)
Explain the relationship between kinetic and potential energy.
Kinetic energy is always greater than potential energy.
They have no relationship, they are completely independent forms of energy.
They are interrelated as potential energy can be converted into kinetic energy and vice versa.
Potential energy is only found in living organisms, while kinetic energy is only found in non-living objects.
If a force of 10 N is applied to move an object a distance of 2 m, what is the work done?
5 J
20 J
200 J
50 J
If an object on the moon has a mass of 3 kg and is at a height of 10 m, what is its potential energy(moon gravity = 1.66)?
294 J
48.9 J
294 N
48.9 N
If a car has a kinetic energy of 55000 J and a speed of 25 m/s, what is his mass?
2200 Kg
88 Kg
176 Kg
110000 Kg
What is energy
the product of the force applied to an object and the distance through which that force is applied
the rate at which work is done or the rate at which energy is transferred or converted
quantity that describes the interaction between two objects
the capacity of a physical system to perform work
