Physics

Question	Answer
General Problem Solving Strategy	1) Read the problem carefully. 2)Draw a diagram of what is happening in the problem. 3)Label all the objects and forces on the object(s) and choose a coordinate system. 4)Identify which principles are used and list your known and unknowns. Put a circle around what you need to find. 5)Choose the equations that will help you find what you need to in the problem. 6)Do the math. 7)Make sure to put units or find them. 8)Plug your answer and make sure it makes sense.
Geocentric Model	Earth is the center of the universe.
Dynamics	Study of force and mass like motion and physical concepts
Kinematics	Discusses motion without discussing what happens to it.
Heliocentric model	Sun is the center of the universe
Frame of reference	Chosen coordinate plane
Displacement	change in position a vector quantity which has an SI unit of m. (delta)x=xf-xi
Vector	quantity with both magnitude and direction
Scalar	quantity with measurement alone
Velocity	SI Unit: m/s xf-xi/tf-ti or (delta)x/(delta)t speed or velocity in everyday math but in physics velocity is a vector quantity
Speed	Average speed=total distance/total time SI Unit: m/s
Acceleration	SI Unit: m/s^2 a=(delta)v/(delta)t or vf-vi/tf-ti
Kinematic equations	v=vi+at Average velocity=(vi+v/2) (delta)x=vit+1/2at^2 (delta)x=(vi+v/2)*t v^2=vi^2+2a(delta)x
