Forces and Motion Flashcards
Vector quantity
A quantity with both magnitude and direction
Scalar quantity
A quantity with magnituded but no direction
3 examples of scalar quantities
Temperature, mass, distance
3 examples of vector quantities
Velocity, displacement, force
Distance
Distance is how far we move from A to B and has no directional sense
Velocity
An object’s speed in a given direction
What is velocity measured in?
It is measured in m/s
Displacement
How far B is from A
Acceleration
The rate of change of velocity
Formula for velocity
Velocity= distance/displacement divided by time
What is acceleration measured in?
It is measured in m/s squared
Formula for average speed
Average speed= distance divided by time
Is speed a vector or scalar quantity?
Scalar
Forces
Motion
