When is the object at rest?

• Never

• Only at 0,0

• from t=0 to t=8 seconds

• from t = 8 to t = 10 s

Choose the true statement

• Indirect measurement is the same as direct measurement

• Indirect measure is never a good idea.

• Indirect measure involves use of measurement and calculation, while direct measurement involves only measurement.

• Direct measure involves use of measurement and calculation, while indirect measurement involves only measurement.

• A = Minimum, B = Maximum

• A = Interpolation, B = Extrapolation

• A = Extrapolation, B = Interpolation

• A = Direct, B = Indirect

Which of the following is an example of a direct measurement?

• Measuring the height of a building using its shadow and trigonometry

• Measuring the mass of an object using a balance scale

• Calculating the speed of a car using the Doppler effect

• Estimating the distance of a star telescope readings
