What is work? energy? power?
How do you calculate work?
For a given motion, how does the direction
of the applied force affect the amount of
work done by the force?
What is kinetic energy? potential energy?
How is net work done on an object related
to its change in kinetic energy?
Find the velocity of an object dropped from
rest from a height h.
Given the mass of an object and the height from which it is dropped, can you calculate its impact force when it hits?
How do seatbelts help protect you from
injury? Do they diminish the work done
on you in a collision? the force?
