Physics Formulas for Game Design Quiz

What is speed?

• A vector quantity that includes direction

• A scalar quantity that refers to how fast an object is moving

• The distance an object travels in a specific direction

• The time it takes for an object to stop

If a swimmer swims at 1 meter per second east, what is being described?

• Speed

• Distance

• Velocity

• Time

What does a fast-moving object have?

• Low speed and covers a smaller distance every second

• High speed and covers a larger distance every second

• Low speed and covers a larger distance every second

• High speed and covers a smaller distance every second

What is necessary to evaluate the velocity of an object?

• Only speed

• Distance and time

• Distance, time, and direction

• Distance and direction

Answer explanation

Speed is distance divided by time. Velocity is speed with direction. Therefore velocity consists of distance, time, and direction.

What is the speed of an object that covers a small distance in a large amount of time?

• High speed

• Zero speed

• Low speed

• Infinite speed

What is the term for how fast an object is moving?

• Velocity

• Distance

• Speed

• Time

Look at the diagram at the top of page 2. In which direction is velocity A measured?

• Southeast

• Northeast

• East

• West

What is the speed of velocity A?

• 15 m/s

• 20 m/s

• 10 m/s

• 5 m/s

Acceleration is a vector quantity because it is what?

• Scalar

• Directional

• Constant

• Variable

What is the change in velocity if a car accelerates from 10 m/s to 26.8 m/s?

• 0 m/s

• 10 m/s

• 16.8 m/s

• 26.8 m/s

Answer explanation

Change is speed is final speed minus initial speed. Since the final speed is 26.8 and the initial speed is 10, the change in speed is 26.8-10, which is 16.8 m/s.
