Scientific notation 1,234 0.000576 3.4 x 10-3 We often use scientific notation to describe quantities in physics, especially for very large or very small numbers. Express the following numbers in scientific notation or convert from scientific notation to a standard number. Do not use a calculator to help. 1,234 0.000576 3.4 x 10-3 Simplify the following, and keep in scientific notation (no calculator!): 4× 10 −9 ∗6× 10 −5 3× 10 −6

Units Some of the primary units used in this course are for the following quantities: time seconds (s) distance meters (m) mass kilograms (kg) Convert the following quantities into the standard units 120 ms 50 km 12 mg 100 km/hr

Units to help solve problems 2 groups of students are working to clean a beach. It takes each group 5 minutes to clean up 200 m of a beach. How long does it take to clean up 2 km of beach? Use rates and units conversion to solve the problem.

Electric car Elon Musk of Tesla said that the Model S in “Ludicrous Speed” mode can go from 0 to 60 mph in 2.8 seconds. Use units analysis, knowing that velocity is m/s and acceleration is m/s2, to find the acceleration of the Tesla. (You can also use a conversion of 1.6 km = 1 mi.)

Vectors Consider the following two vectors: vectors.ppt

Ball in Air Your instructor will show you a movie of a ball being thrown straight up in the air . Draw a complete motion diagram (position, velocity, acceleration) for the ball from the time just after it leaves the hand until just before it is caught. Was your diagram correct? If not what was wrong with it? Does the velocity change? How can you tell? Is the velocity ever zero? How can you tell? Is the acceleration ever zero? How can you tell? Turn-a-round.ppt

Dropped Ball Your instructor will show you a movie a ball that is dropped and then bounces off the floor. Draw a complete motion diagram (position, velocity, acceleration) for the ball. Concentrate on the time just before and after the bounce. Was your diagram correct? If not what was wrong with it? Does the velocity change? How can you tell? Is the velocity ever zero? If so, when is it zero? Is the acceleration ever zero? If so, when is it zero? Turn-a-round.ppt

Car Rebound Your instructor will show you a movie of a cart that rebounds from a spring attached to a wall. Draw a complete motion diagram (position, velocity, acceleration) for the cart. Concentrate on the time just before and after the bounce. Was your diagram correct? If not what was wrong with it? Does the velocity change? How can you tell? Is the velocity ever zero? How can you tell? Is the acceleration ever zero? How can you tell? Turn-a-round.ppt
