Day 5-6 Acceleration Lesson

What does a position versus time graph represent?

• The displacement of an object over time

• The force applied on an object over time

• The acceleration of an object over time

• The velocity of an object over time

How can you find the instantaneous velocity of an object?

• By calculating the area under the curve on a velocity versus time graph

• By drawing a tangent line on a position versus time graph

• By calculating the total displacement divided by total time

• By measuring the object's speed with a speedometer

What does the slope of a position versus time graph indicate?

• Acceleration

• Velocity

• Force

• Displacement

What units are used to express slope in a position versus time graph?

• Meters per second squared

• Meters per second

• Seconds

• Meters

What does a horizontal line on a position versus time graph indicate?

• Constant acceleration

• Constant velocity

• Negative acceleration

• The object is not moving

How do you calculate average velocity?

• Total displacement divided by total time

• Final velocity minus initial velocity

• Initial velocity plus final velocity divided by two

• Change in position divided by change in time

What does a line curving upwards on a position versus time graph indicate?

• The object is moving backwards

• Acceleration

• Constant velocity

• Deceleration

What does a steep slope on a position versus time graph indicate?

• Fast movement

• Slow movement

• No movement

• Backward movement

What does the area under a velocity versus time graph represent?

• Energy

• Force

• Displacement

• Acceleration

What does a negative slope on a velocity versus time graph indicate?

• Positive acceleration

• Negative acceleration

• Constant velocity

• No movement
