Question 1
A) Basics Unit
Length: Meter (m)
Mass: Kilogram (kg)
Time: Second (s)
Electric Current: Ampere (A)
Temperature: Kelvin (K)
Amount of Substance: Mole (mol)
A) Derived Unit
Force: Newton (N)
Pressure: Pascal
Energy: Joule (J)
Power: Watt (W)
Velocity: Meter per second (m/s)
C) Vectors vs Scalars
Vector: A quantity that has both magnitude and direction.
Scalar: A quantity that has only magnitude
D) Way to Represent Vectors
The representation of vector is done by using the arrow. We know that an arrow contains a head and a tail. The head of the arrow denotes the direction of the vector.
E )How do you add up two or more vectors?
add the corresponding components from each vector
B) Prefixes for Units of Measurement
F) Pythagorean theorem: a2 + b2 = c2.
G) Sines: sin A = a/c, sin B = b/c.
Larger than base unit:
Kilo- (k) = 10³
Mega- (M) = 10⁶
Giga- (G) = 10⁹
Smaller than base unit:
Milli- (m) = 10⁻³
Micro- (μ) = 10⁻⁶
Nano- (n) = 10⁻⁹
