Multiple Choice

Which of the following best describes the difference between average speed and instantaneous speed?

• Average speed is measured over a period of time, while instantaneous speed is measured at a specific moment.

• Average speed is always higher than instantaneous speed.

• Instantaneous speed is measured over a period of time, while average speed is at a specific moment.

• There is no difference between average speed and instantaneous speed.

Multiple Choice

How does the slope of a distance-time graph relate to the speed of an object?

• A steeper slope means higher speed.

• A flat line means increasing speed.

• A curved line means constant speed.

• The slope does not relate to speed.

Open Ended

Explain how changes in velocity can occur. Provide examples for each type of change mentioned.

Multiple Choice

When a boat moves across a flowing river, how do you determine its resultant velocity relative to the shore?

• By adding the boat's velocity relative to water and the river's velocity relative to shore using vector addition.

• By subtracting the river's velocity from the boat's velocity.

• By multiplying the two velocities together.

• By only considering the boat's velocity.
