Understanding Motion Maps and Acceleration

What are the three components that motion maps provide information about?

• Position, velocity, and acceleration

• Position, time, and speed

• Acceleration, speed, and time

• Velocity, time, and distance

How does the spacing between dots change on a motion map when an object is speeding up?

• The spacing remains constant

• The spacing gets wider

• The spacing becomes irregular

• The spacing gets narrower

What does the position-time graph look like for an object speeding up?

• A top opening parabola

• An upward sloping line

• A downward sloping line

• A straight horizontal line

What is the definition of acceleration in terms of velocity?

• Change in position over time

• Change in velocity over time

• Change in speed over distance

• Change in distance over time

When calculating acceleration vectors, what operation is performed on the velocity vectors?

• Subtraction of initial from final vectors

• Division of initial by final vectors

• Addition of initial and final vectors

• Multiplication of initial and final vectors

What is the result of adding a velocity vector to its opposite?

• A larger vector

• A smaller vector

• A zero vector

• A negative vector

What happens to the acceleration vector when there is constant acceleration?

• It remains the same size

• It changes direction

• It changes size

• It disappears

In a motion map for steady motion towards an object, what is the acceleration?

• Variable

• Positive

• Negative

• Zero

How are velocity arrows represented in a motion map for steady motion?

• They decrease in size

• They increase in size

• They disappear

• They remain the same size

What does a zero acceleration indicate on a motion map?

• The object is speeding up

• The object is stationary

• The object is slowing down

• The object is moving at a constant speed
