Understanding Motion and Its Concepts

What is the definition of motion in science?

• The ability to see objects

• The change in position of an object over time

• The amount of force applied to an object

• The color of an object

Which of the following is a type of velocity?

• Static velocity

• Average velocity

• Rotational velocity

• Stationary velocity

What is the SI unit of acceleration?

• m/s

• m/s^2

• km/h

• s/m

Which term describes the rate at which velocity changes?

• Speed

• Acceleration

• Displacement

What is the formula for average velocity?

• Total distance / Total time

• 4 m/s^2

• 8 m/s^2

Which of the following is an example of non-uniform motion?

• A train moving at a constant speed

• A car slowing down at a traffic light

• A clock’s hand moving at a steady rate

• A person walking at the same pace

A cyclist travels 60 meters east in 15 seconds. What is the cyclist’s average velocity?

• 2 m/s east
