1.3-1.10 movement and position Flashcards
1
Q
how do distance time graphs work
A
the gradient of the line is equal to the speed of the object. The greater the gradient (and the steeper the line) the faster the object is moving
2
Q
how do you calculate speed?
A
speed = distance/time
3
Q
how do you calculate acceleration?
A
acceleration= change in velocity/time
4
Q
how do velocity time graphs work?
A
A horizontal line on a velocity-time graph, shows that the object is at constant velocity, but a sloping line on a velocity-time graph, shows that the object is accelerating. The gradient of the line is equal to the acceleration
5
Q
how do you calculate final speed?
A
final speed^2 = initial speed^2 + (2 x acceleration x distance moved)
