What is the relationship between work and kinetic energy?

According to the work-energy theorem, what does the net force on an object equal to?

What is the formula for work done by a net force on an object?

What is the formula for calculating the final speed of an object using kinematics equations?

What is the formula for calculating the change in kinetic energy of an object?

In the given example problem 1, what is the work done by the force when calculated using force times displacement?

What is the work done by a 40N force on a 5kg object when calculated using the change in kinetic energy formula?

Your backpack weighs 20 newtons. You lift it 1.5 meters off the floor.

Your backpack weighs 20 newtons. You carry it for 100 meters.

Does potential energy apply to moving objects?

Kinetic energy increases with...

What is the kinetic energy of the car if it has a mass of 1,100 kilograms and is
moving at 35 m/s?

A zombie runs by at 12 m/s and has 8200 Joules of kinetic energy. What is the zombie’s mass?

If an object is not moving, is work still being done?

A force can____________.

True or false: An object resting on the ground can move without force.
