How to express m/s in physics?
m s^-1
Equation for scientific notations + example
a x 10 ^b
e.g. 250000= 2.5 x 10^5
How to find uncertainty?
Is half the smallest marking on the instrument used to measure data.
e.g. ruler= 65 cm ± 0.5 cm
What is distance + symbol?
Distance (d) is how far an object traveled in total)
What is displacement + symbol?
Displacement (s) is the net distance and direction traveled from start to the finish point.
what are scalars?
quantities fully described by their magnitude (size) e.g. distance, mass, energy, speed
what are vectors?
quantities that have a distance and magnitude e.g. displacement, velocity, force, acceleration
speed equations + example
s=d/t
Give example
velocity equation + example
v= displacement (s)/t
Give example
acceleration equations + example
a= v-u/t
Give example
Conversion equation between km/h and m/s
km/h divided by 3.6 = m/s
m/s times 3.6= km/h
