Physics in the Universe: Unit 1 Test Review

An ant is seen walking along a meter stick.  He starts at the 10 cm mark.  He then walked down to the 37 cm mark.  He turns around and walks back to the 21 cm mark.  What is his displacement? INCLUDE NUMBER, UNIT, and DIRECTION ex 17cm,West NO SPACES

Find the distance a bike travels in 2 hours if it is traveling at a speed of 25 km/hr

How long would it take a van to travel 2,400 m if its speed is 67.0 m/s?

Using the graph , what is the displacement of the object for segment A? Justify your answer.

Bart Simpson runs 25 m east and then runs 40 m west.  If it takes him 60 seconds to do this, what is his velocity?

Match the following terms to their units

• s

• Time

• m/s

• Velocity

• m/s^2 OR m/s/s

• Acceleration

• m

• Displacement

1. A physical quantity that has magnitude and units is called

• 1. fundamental unit   

• 1. derived unit   

• 1. scalar   

• 1. vector

1. A runner traveled 26 km east then backtracked 30 km before stopping.  The displacement from the original position is 

• +56 km

• +4 km

• -4 km

• -56 km

1. Velocity, acceleration, and displacement are all examples of

• 1. scalar quantities

• 1. vector quantities

• 1. magnitude quantities

• 1. directional quantities

1. On a position-time graph, the slope of a tangent to the curve is the _________________at that instant.
