What is a vector value
A quantity that has both a magnitude and a direction
What is a scalar value
A quantity that only have a magnitude
Which one is scalar /vector: Distance and Displacement
Distance–> scalar
Displacement–> vector
Which one is scalar /vector: Speed and velocity
Speed –> scalar
Velocity –>Vector
Which one is scalar /vector: Mass and Weight
Mass –> scalar
Weight –> vector
What is the formular for speed
Speed = distance /time
If you were born and died in the same room in the same hospital, what is the displacement of you
0 meter
For a distance time graph, what does the gradient show
The speed
If the gradient of the distance time graph is steeper, is the speed faster or slower
Faster
If the line of the distance time graph is straight, what does this show about the speed
Constant speed
If the line of the distance time graph is flat, what does this show about the speed
The object is stationary
If the line of the distance time graph is curve, what does this show about the speed
The object is accelerating
What does the gradient of velocity time graph show
The rate of acceleration
What is the unit of acceleration
m/s^2
What does the area under the line show in a velocity time graph
The displacement
Does Suvat equation have to be a constant acceleration
Yes
What does the u in suvat means
Initial velocity
What does the s in suvat means
Displacement/distance
