Study Notes
Vector Components
- A vector is a Latin word that means "carrier", carrying a point A to point B.
Vector Applications
- In a car, if there is no slipping between the wheels and the road, the arc length moved by a marker on the outermost radius of the wheel is equal to the distance traveled by the car.
- In this case, the distance traveled by the car is 120m.
Sinusoidal Oscillations
- A body can be set into oscillation by initially stretching a spring a certain distance (x= xo) and then releasing it at t=0.
- The body may undergo sinusoidal oscillations, which can be described by a function such as Eq. 3.9.
