PS Final : Physics

Physical Science Final Exam Review for Physics Part

guidelines for describing object's specific location in space and time frame of reference
Force that always opposes motion friction
Law of Motion: F = ma 2nd
Anything that can cause an object to change its motion force
Law of Motion: "For every force, there is an equal and opposite force" 3rd
Displacement divided by time velocity
Quantity that has magnitude only scalar
Distance divided by time speed
Law of Motion: "An object in motion, will stay in motion until acted on by a net force" 1st
Quantity that has magnitude and direction vector
Shortest distance between 2 points displacement
Force that causes downward acceleration gravity
Force times distance work
Path of motion for all projectiles curved
Upward force opposing gravity air resistance
mass X gravity X height (object not moving) PE (potential energy)
half the mass X velocity squared (moving object) KE (kinetic energy)
sum of PE + KE ME (mechanical energy)
SI unit for work and energy J (Joules)
SI unit for force and weight N (Newtons)
SI unit for mass kg (kilograms)
Value for gravity on Earth 10 m/s/s
Amount of work done if object does NOT move Zero
