What is the formula for average acceleration?

What is Jo's average speed during the entire walk?

• 2.5 m/s

• 3.5 m/s

• 1.75 m/s

• 1.5 m/s

What is Jo's average velocity during the entire walk?

• 1.5 m/s East

• 0.5 m/s East

• 1.0 m/s East

What is the main difference between speed and velocity?

• Speed includes direction, velocity does not.

• Speed is direction aware, velocity is direction ignorant.

• Speed is direction ignorant, velocity is direction aware.

• Speed and velocity both include direction.

Which of the following is an example of velocity?

• 5 m/s

• 10 m/s

How is speed calculated?

What does velocity measure that speed does not?

• Time

• Distance

• Direction

• Mass

In the formula Δt = t - t₀, what does t₀ represent?

• The time at the end of the motion

• The average speed

• The time at the beginning of the motion

• The acceleration

What does displacement (Δx) tell us about an object?

• The speed of the object

• The distance the object traveled

• How far the object ends up from its starting point

• The time taken by the object to move

What does X represent in the context of displacement?

• Initial velocity

• Initial position

• Final position

• Acceleration
