What is down?
Kinetic Energy of an object
What is
K=(1/2)mv^2
The length of time for the entire AP Physics 1 exam.
What is 3 hours
A problem asking about acceleration that doesn't include any forces.
What are kinematic formulas?
When an object moves some distance due to a constant force that acted upon it, this has been done
What is work?
Kinematic equation to find the velocity of an object without knowing the time.
v^2 = v_0^2 + 2ad
The number of FRQ questions on the AP Physics 1 exam.
