Description

!

Midterm Review ! ! Chapter one- introduction! • Metric conversions ! • Vectors! Know what is a vector and what is a scalar !

‣ Head to tail method ! ! Chapter two- kinematics (straight line motion) ! • In the y direction: a is always g=-9.8m/s^2 ! • Told a=0, constant velocity- could be moving or could be stationary !

• Motion graphs ! ! ! ! ! ! ! ! ! ! ! ! ! ! Chapter three- Projectile motion! ⭐ separate x and y components! 1.% "Off-cliff": object is projected horizontally ! ! X: ! Y:! • a=0, constant velocity ! • a=g=-9.8m/s^2 ! ! • Vo=0 Time is the same 2. Projected at an angle! ! X:! Y:! • a=0! • a=g=-9.8m/s! • Vox ! • Voy! ! • Vtop=0 (only y)! ! Time is the same

Chapter four and five- Newton's Laws/Dynamics ! ! Fnet=ma! A net force creates an acceleration on an object and the object goes in the direction of the force ! ⭐ Free body diagram- show all the forces! % Fn is always perpendicular to the support ! ! ! ! ! ! ! ! ! • Equilibrium means no net force, thus not accelerating, but still moving (if moving)! • Elastic forces: Hooke's law!

Chapter six- circles and gravity! ! Fc=ma(c)! • In circular motion- traveling at constant speed is accelerating ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! !

! Chapter six and seven- work, energy, and power all scalar ! ! ! ! ! ! ! ! ! ! Conservation of Energy ! Avoid mass interactions: collisions and explosions ! ! ! ! Without friction- ! ! TE1=TE2! ! ! ! With friction- ! ! ! ! TE1-Wf=TE2 ! ! (losing mechanical energy to heat) ! ! Chapter eight- Momentum vectors! ! ! ! ! Any collision or mass interaction: momentum is conserved...
