Motion
- key terms
- SPEED
- is distance travelled per second
- is distance travelled per second
- VELOCITY
- is displacement
travelled per second
- it needs a direction
- it needs a direction
- is displacement
travelled per second
- VECTOR
- has magnitude (size)
and direction
- EG. velocity,
acceleration,
displacement
- has magnitude (size)
and direction
- SCALAR
- has a magnitude only
- EG. speed, distance, height, mass, time
- EG. speed, distance, height, mass, time
- has a magnitude only
- ACCELERATION
- is the rate of change in velocity
- is the rate of change in velocity
- SPEED
- Equations
- SPEED = distance / time
- VELOCITY = displacement / time
- ACCELERATION =
change in velocity /
change in time
- SPEED = distance / time
- DISTANCE-TIME graphs
- SPEED and GRADIENT are the same
- GRADIENT = change in y / change in x
- GRADIENT = change in y / change in x
- work out speed
- SPEED and GRADIENT are the same
- VELOCITY - TIME graphs
- work out acceleration
- ACCELERATION and GRADIENT are the same
- GRADIENT = change in y / change in x
- = change in velocity / change in time
- = acceleration
- = acceleration
- = change in velocity / change in time
- GRADIENT = change in y / change in x
- You can also work out the distance travelled
- area = speed x time = distance
- its the area under the graph of the section you want to find out
- its the area under the graph of the section you want to find out
- area = speed x time = distance
- work out acceleration
