A ball is dropped from above the ground. Assuming gravity iswhat is its final velocity? We can use potential energy to solve. Remember, your height and your gravity need to have the same sign, as they are moving in the same direction downward. Either make them both negative, or use an absolute value. Using conservation of energy, we know that. This tells us that the potential energy at the top of the hill is all converted to kinetic energy at the bottom of the hill.
We can substitute the equations for potential energy and kinetic energy. A ball rolls down a hill with an initial velocity of. What is its maximum velocity? For this problem, the ball starts with both potential and kinetic energy. The point of maximum velocity will have no potential energy.
We can solve setting the initial energy and final energy equal, due to conservation of energy. Plug in the high school physics essay values and solve for the final velocity.
Remember, high school physics essay, when the ball is on the ground it has a height of zero. A book falls off of a high table. If the book weighswhat will its final velocity be right before it hits the ground? The book initially has only potential energy, high school physics essay.
Right before it hits the ground, all the potential energy will be converted to kinetic energy. We can use the law of conservation of energy to set the initial and final energies equal. If the book weighswhat will its kinetic energy be right before it hits the ground? Initially, the book has only potential energy. Right before it hits the ground, all the potential energy will have converted to kinetic energy. The two values will be equal based on the conservation of energy. A rock is dropped from a helicopter hovering at above the ground.
If the rock weighswhat is its kinetic energy right before it hits the ground? Right before it hits the ground, the initial potential energy and the final kinetic energy will equal each other due to conservation of energy, high school physics essay. Plug in the values given. Remember that height is the change in height. Since the rock is headed downward, the height will be negative. A pendulum with string length is dropped from rest. If the mass at the end of the pendulum iswhat is its maximum velocity?
The maximum velocity of the pendulum will be when the object has only kinetic energy. Using conservation of energy, we can set our initial potential energy to equal our "final" kinetic energy. A book high school physics essay off the top of a bookshelf. What is its final velocity right before it hits the ground? Remember the law of conservation of energy: the total energy at the beginning equals the total energy at the end, high school physics essay.
In this case, we have only potential energy at the beginning and only kinetic energy at the end. The initial velocity is zero, high school physics essay the final height is zero. If we can find the potential energy, we can find the kinetic energy. The formula for potential energy is. Using our given values for the mass, height, and gravity, we can solve using multiplication.
Note that the height becomes negative because the book is traveling in high school physics essay downward direction. The kinetic energy will also equaldue to conservation of energy. Using this value and our given mass, we can high school physics essay the velocity from our original kinetic energy equation. Since we are taking the square root, high school physics essay, our answer can be either negative or positive.
The final velocity of the book will be in the downward direction; thus, our final velocity should be negative. What is its velocity right before it hits the ground?
An orange falls off of a tree tall. What is the final velocity of the orange before it hits the ground? High school physics essay this problem, we need to use the law of conservation of energy, high school physics essay.
Since we are only looking at gravitational energy here and the orange starts at rest, we can say that the initial potential energy is equal to the final kinetic energy. From here, we can expand the equation, using the formulas for gravitational potential energy and kinetic energy. Since displacement is a vector magnitude and direction we need to be clear that it travels down.
At this point, we need to remember that the square root of a positive number can be high school physics essay positive or negative. Our velocity is a vector, so we will need to make sure we pick the answer choice with the appropriate direction.
Since the orange is traveling downward, we know our final velocity must be negative. A baseball has a mass of. If a high school pitcher can throw a baseball atwhat is the approximate kinetic energy associated with this pitch? Before we can plug in our given values, we must convert the mass from grams to kilograms. Remember, the SI unit for mass is kilograms, so most calculations will require this conversion.

High School Physics Help » Energy and Work » Energy » Calculating Kinetic Energy. Example Question 1 : Calculating Kinetic Energy. Possible Answers:. Correct answer:. Explanation : We can use potential energy to solve. The masses cancel out.
Plug in the values, and solve for the velocity. Report an Error. Explanation : For this problem, the ball starts with both potential and kinetic energy. The masses will cancel out from all of the terms. Explanation : The book initially has only potential energy. Use the equations for potential energy and kinetic energy. Now, plug in the values given to you in the problem and solve for the velocity. 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.

Excel High School offers online high school courses that meet and exceed State standards for high school graduation. All of our courses are easy to navigate and ensure that students’ master the course subject matter. We also reinforce learning at the very basic level, ensuring that students fully comprehend the course materials, before moving on to the next level Standard High School Curriculum. Below is information on the typical classes a high school student will be expected to take, organized by subject. Each subject includes classes that are required to graduate high school, classes colleges expect students to have taken, and suggestions for ways to impress by going beyond these expectations. English High School Physics can be taught in two ways: either as a stand-alone course, or as a precursor to AP Physics B. In schools that offer the AP course, the High School Physics curriculum can be more focused, targeted at introducing material that will be expanded upon later. In schools where the AP course is not offered, High School Physics may
