If a particle is moving, it has kinetic energy. Kinetic energy is the energy of motion, and it depends on the speed and mass of the particle. It is given by the formula Ek = -1/-mv², where Ek is the kinetic energy, m is the mass, and v is the speed of the particle. The formula for kinetic energy has some important features to keep in mind. • Kinetic energy, and every other type of energy as well, is a scalar quantity, given by only a single number. Energy does not have a "direction", unlike a vector quantity. (This is in contrast to the vector quantity momentum, which you might have already studied.) • Kinetic energy, in particular, is always a positive number. (Note the speed v is the magnitude of the vector velocity, and therefore is positive. But even if it were a negative number, squaring it would always lead to a positive result.) • Kinetic energy depends on the square of the speed. (This is in contrast to the magnitude of momentum, mv, a quantity you may have already studied,…

is acceleration, 5. The equation for kinetic energy is KE=: 2 m•v. Solve for v, given KE and m. Guide Questions: 1. Some hummingbirds beat their wings more than 50 times per second. A scientist is measuring the time it takes for a hummingbird to beat its wings once. Which fundamental unit should the scientist use to describe the measurement'? Which factor of 10 is the scientist likely to use to describe the motion precisely? Identify the metric prefix that corresponds to this factor of 10. Page UIC-SHS 2020-2021
• One one sheet of college-lined paper, show that both sides of each of the following equations are equivalent to each other. This is a REQUIRED assignment and is not extra credit! • Start with the more complicated side on the RIGHT and try simplifying it to the LEFT side. • Take note that this is NOT an equation! So you cannot do any operation to both sides of it until you have proven both are equivalent to each other! • You may work together with your classmates but I highly recommend seeing the tutors im or myself during regularly scheduled office hours for help with this assignment. • You might need the following basic definitions of the following units: • Newton (N) = kg · m/s² • Joule (J) = N ·m = kg · m² /s?

If you have spent much time driving, you probably have a good sense of speeds between about 10 and 70 miles per hour. But what are these in meters per second? What do we mean when we say that something is moving at 10 m/s? To get a better sense of what these values really mean, do some observations and calculations on your own: • calculate typical car speeds in meters per second • estimate jogging and walking speed by timing yourself; convert the measurements into both m/s and mi/h • determine the speed of an ant, snail, or falling leaf
