3rd Quarter Review

It is completely specified by magnitude alone. They are described with a single number.

• Scalar Quantities       

• Vector Quantities                  

• Longitudinal waves

• Transverse waves

It is a physical quantities that require both magnitude and direction for their specification

• Scalar Quantities

•  Vector Quantities

• Longitudinal waves

•  Transverse waves

It is the total path length that the object traveled.

• Frequency

• Loudness        

• Distance

• Displacement

The distance traveled divided by how long it takes.

• Air      

• Vacuum          

• Speed

• Velocity

It is the measure of an object’s change in position.

• Frequency      

•  Loudness

• Distance

• Displacement

The speed and direction of the moving object is called ______.

• Air  

• Vacuum

• Speed

• Velocity

What is speed?

• a) Speed is just how fast something is moving.

• b) Quantities that have direction are called vectors

• c) A negative velocity does not mean an object is moving slower than zero cm/s.

• d) Quantities that have direction are called vectors

It is defined as the rate of change in an object's velocity.

• Amplitude

•  Wave

• Acceleration

• Crest

Deceleration means the velocity reduces with time

• Negative Acceleration

• Positive Acceleration

• Uniform Acceleration

• Non- Uniform Acceleration

The velocity increases with time.

• a) Negative Acceleration

• b) Positive Acceleration

• c) Uniform Acceleration

• d) Non- Uniform Acceleration
