What is the main focus of Chapter 2 in the text?

• Electricity and Magnetism

• Physical Quantities

• Chemical Reactions

• Biological Systems

What is the purpose of Activity 1 in Chapter 2?

• To share teaching experiences related to measurement

• To draw a concept map on physical quantities

• To discuss traditional measuring units

• To measure the mass of objects

How are scalar and vector quantities defined in the text?

• Scalar quantities have magnitude only, while vectors have magnitude and direction

• Scalar quantities have direction only, while vectors have magnitude and direction

• Scalar quantities have magnitude and direction, while vectors have magnitude only

• Scalar quantities have magnitude and direction, while vectors have direction only

What is the algebraic method of vector addition based on?

• Breaking vectors into horizontal and vertical components

• Using the triangle law of vector addition

• Drawing vectors on a coordinate plane

• Measuring the angle between vectors

What is the difference between distance and displacement?

• Distance is always positive, while displacement can be negative

• Distance is measured in meters, while displacement is measured in kilometers

• Distance is a scalar quantity, while displacement is a vector quantity

• Distance is a vector quantity, while displacement is a scalar quantity

How is velocity defined in the text?

• The distance traveled divided by time

• The speed of an object without direction

• The magnitude of displacement

• The rate of change of speed

What is the main difference between speed and velocity?

• Speed is always positive, while velocity can be negative

• Speed is distance traveled per unit time, while velocity is displacement per unit time

• Speed is a vector quantity, while velocity is a scalar quantity

• Speed includes direction, while velocity does not

What is the purpose of Activity 4 in Chapter 3?

• To discuss natural disasters

• To differentiate between speed and velocity

• To calculate average speed

• To measure the instantaneous speed of a vehicle

How is instantaneous velocity defined in the text?

• The average velocity over a period of time

• The velocity of an object at a specific instant in time

• The speed of an object without direction

• The magnitude of displacement

What is the relationship between velocity and speed?

• Velocity is speed in a given direction

• Speed is always greater than velocity

• Velocity is always greater than speed

• Speed is velocity in a given direction
