Velocity and Momentum

If an object is moving at 2 m/s towards a porcelain vase, do you think it will have enough momentum to break the vase?

• Yes, it will have enough momentum to break the vase.

• No, it will not have enough momentum to break the vase.

• It depends on the mass of the object.

• It depends on the material of the vase.

Velocity and speed are different in that:

• velocity includes direction while speed does not

• speed includes direction while velocity does not

• both velocity and speed include direction

• neither velocity nor speed include direction

Describe the movement of the continents over the past 250 million years. According to the theory of plate tectonics, the continents are moving constantly over Earth’s surface. The movement is shown in the figure below. The changes are so slow that we do not notice them.

• The continents have remained in the same position over the past 250 million years.

• The continents have moved constantly over Earth's surface according to the theory of plate tectonics.

• The continents have moved rapidly over Earth's surface, noticeable within a human lifetime.

• The continents have moved only once in the past 250 million years.

The speed of the movement of Earth’s plates is measured in centimeters per year instead of in meters per second because:

• it is a very slow process and centimeters per year is a more appropriate unit.

• it is a very fast process and meters per second is too large a unit.

• centimeters per year is the standard unit for all geological processes.

• meters per second is not a recognized unit for geological measurements.

What is the momentum of a bicycle with a mass of 18 kg traveling at 20 m/s?

• 360 kg·m/s

• 380 kg·m/s

• 400 kg·m/s

• 420 kg·m/s

Compare: Which has more momentum, a car traveling at 12 km/h or a bicycle traveling at the same speed?

• A car traveling at 12 km/h

• A bicycle traveling at 12 km/h

• Both have the same momentum

• Cannot be determined

Velocity is speed with __________________________.

• a unicycle helmet

• direction

• fight
