CP Ch01.2 Speed and Velocity

Which of these is true?

• The greater the distance traveled in a short amount of time is the fastest

• The less time you travel in a smaller distance will be the fastest

• Meters is a measurement of speed

• Speed is calculated as time divided by displacement, while velocity is time divided by distance.

What does the "/" symbol mean ?

• exponent

• addition

• multiplication

• per

In the picture, what is the displacement of the trajectory?

• 0 km

• the addition of all the trajectory

What is the difference between distance and displacement?

• Distance is how far something travels, while displacement is the distance before and after traveling.

• Distance is the same as displacement.

• Distance is the distance before traveling, while displacement is the distance after traveling.

• Distance is the displacement divided by time.

Who was the first to measure speed by considering the distance covered and the amount of time it takes?

• Newton

• Einstein

• Galileo

• Tesla

What is the difference between constant speed and constant velocity?

• Constant speed means steady speed, while constant velocity means steady speed with direction.

• Constant speed means motion in a straight line at constant speed, while constant velocity means steady speed.

• Constant speed means motion in a straight line at varying speed, while constant velocity means motion in a straight line at constant speed.

• Constant speed means steady speed, while constant velocity means motion in a curved line at constant speed.

What is the difference between the equations for speed and for velocity?

• speed requires time while velocity does not

• speed can be written as m/h while velocity cannot

When driving a car and you make a turn, which one of these is changing?

• speed

• velocity
