T4 L 2 Speed, Velocity, and Acceleration

How can you interpret graphs to determine acceleration?

• By looking at the slope of the graph

• By counting the number of points on the graph

• By measuring the area under the graph

• By checking the color of the graph

If a car travels 3 kilometers in 1 hour, 50 kilometers in 1 hour, and 211 kilometers in 2 hours, what is the total distance traveled?

• 50 km

• 211 km

• 264 km

• 300 km

What is the formula for calculating slope? found on Page 201

• Slope = Run / Rise

• Slope = Rise / Run

• Slope = Rise + Run

• Slope = Run - Rise

What part of velocity is important for the formation of a marching band that is not shown by a distance-versus-time graph?

• Speed

• Direction

• Acceleration

• Time

Do all of the members of a marching band have to move at the same velocity at all times?

• Yes, to maintain the formation

• No, they can move at different velocities

• Yes, to avoid collisions

• No, only the leader needs to maintain velocity

If a thunderstorm is traveling at a speed of 25 km/h, what additional information do you need to know to prepare for the storm?

• The storm's temperature

• The storm's direction

• The storm's size

• The storm's humidity
