1
Q
What is distance?
A
How far an object moves
Scalar quantity
2
Q
What is displacement?
A
How far an object moves in a straight line
Vector
3
Q
What is speed?
A
Scalar
4
Q
What is velocity?
A
Vector
5
Q
Whats an experiment to measure speed?
A
Light gates
The length of a piece of card is measured with a ruler, and attached to a trolley.
The trolley is rolled down a ramp so that the card passes through the light gate.
6
Q
Whats the equation for speed?
A
Speed = Distance / TimeW
7
Q
What are the 2 equations with acceleration?
A
(Final speed)2 – (initial speed)2 = 2 × acceleration × distance.
v2 - u2 = 2ax
Final speed = initial speed + (acceleration x time).
v = u + at
