Acceleration
Objectives
1. define acceleration
2. list meaning of variables in acceleration equation
3. use acceleration equation
Acceleration
Introduction
rate of change of velocity
can be an increase in velocity or a decrease in
velocity (deceleration
Center of Mass, Torque and
Rotational Inertia
Objectives
1. Define center of mass, center of gravity, torque,
rotational inertia
2. Give examples of center of gravity
3. Explain how center of mass affects rotation and
toppling
4. Write the equations for t
Free Fall
Objectives
1.)
2.)
3.)
4.)
define free fall
explain that all falling objects accelerate
agree that all objects fall at the same rate
write the free fall equations
Free Fall
Introduction
Free Fall
motion caused only by gravity
all objects fall
Angle Range Calculation
Muzzle velocity is a vector
Speed is magnitude
Angle of elevation gives direction
North, south, east, west doesnt matter
Need to resolve the vector into its components
Vertical component determines the time in the air
