Motion

Why is tectonic plate motion measured in centimeters per year?

• Their motion is too fast

• The units are smaller

• Their movement is very slow

• It’s easier to compare to meters

What affects how motion is described?

• The object's mass

• The reference point chosen

• The object's temperature

• The color of the object

When a car is speeding up, in which direction are its acceleration and velocity?

• Opposite directions

• Perpendicular directions

• Random directions

• Same direction

What do both velocity and momentum have in common?

• They are measured in kg

• They have only magnitude

• They are measured in hours

• They have direction and size

Why does a delivery truck have more momentum than a car at the same velocity?

• It is higher

• It is faster

• It is longer

• It has more mass

What is the rate of change of velocity called?

• Speed

• Distance

• Acceleration

• Time

What does velocity include?

• Only speed

• Only direction

• Both speed and direction

• Neither speed nor direction

What does acceleration mean in terms of an object's motion?

• An object is moving at a constant speed

• An object is changing its velocity

• An object is not moving

• An object is moving in a straight line

What is the focus of the lesson on acceleration?

• How to drive a car

• How acceleration, time, and velocity are related

• How to build a car engine

• How to stop a car

What should you do as you read the lesson according to the study coach?

• Memorize every word

• Make an outline of the important information

• Ignore the diagrams

• Write a summary
