How much kinetic energy does it have there

A 71 kg man walking at 1. A 71 kg man running at 5. A kg car 2 tons travelling at J Correct! Notice that, since velocity is squared, the running man has much more kinetic energy than the walking man. Also notice how much energy the moving car has. No wonder accidents can cause so much damage!

At least one of the values you entered is incorrect. Example Question 4 : Calculating Kinetic Energy. Explanation : Initially, the book has only potential energy. If we solve for potential, we can find kinetic energy. Explanation : Right before it hits the ground, the initial potential energy and the final kinetic energy will equal each other due to conservation of energy. If we solve for initial potential, we can find final kinetic energy.

Multiply and solve. Example Question 6 : Calculating Kinetic Energy. Explanation : The maximum velocity of the pendulum will be when the object has only kinetic energy. Plug in the given values and solve for the velocity. Example Question 7 : Calculating Kinetic Energy. Explanation : The relationship between velocity and energy is: We know the mass, but we need to find the total kinetic energy.

Example Question 2 : Calculating Kinetic Energy. Explanation : For this problem, we need to use the law of conservation of energy. Notice that the mass cancels out form both sides. Explanation : To solve for the kinetic energy, we will need to use the equation: Before we can plug in our given values, we must convert the mass from grams to kilograms. Now we can use this mass and the given velocity to solve for the kinetic energy.

Asteroids - packed relatively close to one another in the asteroid belt - can collide with one another or graze past each other as their orbits shift over time.

This may result in an asteroid bumping or bouncing out of Its previous orbit and changing into a different orbit that is called 'Earth-crossing. The Sun is shown in red, the Earth in green, and the asteroid in yellow. Also, in this figure, objects like Mercury, Venus, Mars, and the asteroids are not included for simplicity.

As you can see, as the Earth and the asteroid go around the Sun, there is some chance that they may be in the same place at the same time one day and thus an energetic collision may take place. We are going to consider what happened in Alabama during the age of dinosaurs specifically about 83 million years ago when an asteroid about m in diameter struck central Alabama.

This event occurred about 20 km north of Montgomery, Alabama, near the town of Wetumpka. You should go to this link to read more about this event before continuing this laboratory: Click Here. When you have finished reading this on-line article at the Encyclopedia of Alabama web site, you will be ready to do the data collection activity in your lab book. Please read and study the article above, because it will be covered along with the material above on your laboratory quiz.
