Physical quantities Chapter 1 Flashcards
What is the unit for electric current?
ampere (A)
What is the unit for time?
The unit for time is second (s).
What are the 4 basic base quantities in the International System of Units (SI)?
- Length
- Mass
- Time
- Electric current
Is displacement a scalar or vector quantity?
Displacement is a vector quantity
What is the formula for force?
Mass × Acceleration
What is the unit for force?
The unit for force is newton (N)
Is time a scalar or vector quantity?
Time is a scalar quantity
What is the unit for mass?
The unit for mass is kilogram (kg)
What is an oscillation?
An oscillation is the motion of an object that moves back and forth between two points (like a pendulum swinging from side to side)
What is the formula for acceleration?
change in velocity / time taken
Is mass a scalar or vector quantity?
Mass is a scalar quantity
What is the difference between speed and velocity?
Speed is the rate of change of distance (scalar). Velocity is the rate of change of displacement (vector).
Convert 2500 centimeters to meters
2500 centimeters = 25 meters
Is velocity a scalar or vector quantity?
Velocity is a vector quantity.
Convert 3 kilometers to meters
3 kilometers = 3000 meters
Convert 500 grams to kilograms
500 grams = 0.5 kilograms
Convert 3.5 hours to minutes
3.5 hours = 210 minutes
Is temperature a scalar or vector quantity?
Temperature is a scalar quantity
What is the unit for time?
The unit for time is second (s).
What is the formula for acceleration?
Change in velocity / time taken
What is the formula for velocity?
Mass × Length / Time²
How long does it take for ONE complete oscillation of a simple pendulum?
It takes the time for the pendulum to go from point A to point B, then to point C, and back to point B, and finally return to point A. This is one full oscillation. Basically, back to where it started.
What is the unit for velocity?
The unit for velocity is meters per second (m/s).
Convert 1000 milliliters to liters
1000 milliliters = 1 liter
