- physics 2A
- velocity and distance-time graphs
- equations
- speed=distance/time
- important notes
- gradient=speed
- physics 2A
- velocity and distance-time graphs
- equations
- speed=distance/time
- important notes
- gradient=speed
- flat sections are when its stationary
- straight up or down mean its at a constant speed
- the steeper the faster
- downhill means its going towards the start point
- curves represent acceleration or de-celleration
- gradient=speed
- equations
- acceleration and velocity-time graph
- Equations
- acceleration=change in velocity/time taken
- important notes
- flat sections represent steady speed
- the steeper the graph the greater the acceleration or deceleration
- downhill sections represent deceleration
- the area under any sections of the graph is equal to the distance travelled in the time frame
- the curve means changing acceleration
- Equations
- forces
- resultant
- real situations there are two forces acting on an object along any direction.
- the overall effect of these forces will decide its movement, acceleration or deceleration or steady speed
- gravitaional
- energy is due to height
- measured in joules
- earths gravitational field strength is about 10 N/Kg
- resultant
- kinetic energy
- kinetic energy transferred is work done
- energy of movement
- when something falls, it converts potential energy into kinetic
