Study Notes
- Motion is a change in position, describable via distance moved or displacement
- Motion can be uniform or non-uniform, depending on constant/changing velocity
- Speed: distance covered per unit of time
- Velocity: displacement per unit of time
- Acceleration: change in velocity per unit of time
Graphs for motion
- Graphs can represent uniform/non-uniform motion
- Uniformly accelerated motion uses these equations:
- v = u + at
- s = ut + (1/2)at²
- 2as = v² - u²
- u = initial velocity
- v = final velocity
- a = uniform acceleration
- t = time
- s = distance in time t
Uniform Circular Motion
- Object moves in a circular path at a uniform speed
- Speed is calculated by v = 2Ï€r/t
- r = radius
- t = time
