2
Q
What is the definition of Vector?
A
A quantity that consists of a magnitude (size) and direction
3
Q
What is the definition of Speed?
A
The distance travelled per unit time. It is a scalar quantity
4
Q
What is the definition of Velocity?
A
The displacement travelled per unit time
5
Q
What is the definition of acceleration?
A
The change in velocity per unit time. It is a vector quantity and is given by the gradient of the line on a velocity-time graph.
6
Q
Describe an experiment to measure the acceleration of an object down a slope
A
Measurments: Length of mask (in metres) Time to cut the first lightgate t1 Time between the two lightgates t2 Time to cut the second light gate
Method:
Determine the initial velocity
Determine the final velocity
Determine the acceleration of the mask
