A ball is thrown horizontally from a cliff at a speed of 15 ms and strikes the ground 45 meters from the base of the cliff How high was the cliff rounded to the nearest meter?
Answer: 44 meters
What does path independence of line integral physically mean?
For a physical meaning, take potential energy as an example. To raise an object from one position to another position one meter higher takes a certain amount of energy - the potential energy of the object increases. The amount of energy is independent of the path the object takes - whether it goes straight up, in zigzag, etc.
If you want to lift a 5kg box to the height of meter how much work must be done?
Did you say one meter ?You'll have to give the box 49 joules of additional gravitational potential energy.But since the human muscular system is not 100% efficient, you'll have to spendsomewhat more energy than that in order to do the job. The additional energythat you put into the effort will show up in the form of elevated body temperature,increased heart rate and blood pressure, and warm perspiration on your brow.
What is The Function of Meter?
it is use to measure electric potential (voltage).
What is potential gradient?
The rate of change of potential with respect to distance is called potential gradient. its unit is volt per meter or newton/coulomb.
Why is the gravitational potential energy of an objects 1 meter above the moons surface less than its potential energy 1 meter above Earths surface?
because the value of gravitational force of earth is greater than that of moon.
Why is the gravitational potential energy of an object 1 meter above the Moon's surface less than its potential energy 1 meter above Earth's surface?
There is less gravity on the Moon. Gravitational potential energy can be calculated by multiplying weight x height, or the equivalent mass x gravity x height.
What is the rocks gravitational potential energy if it is at 100 meter height the rock mass is 1kg'?
At 100 meters this rock's potential energy is 980 joules.
Why is gravitational potential energy of an object 1 meter above the Moon's surface less than it's potential energy 1 meter above earth's surface?
There is less gravity on the Moon. Gravitational potential energy can be calculated by multiplying weight x height, or the equivalent mass x gravity x height.
What is a skier's gravitational potential energy at 10 meters?
Just use the formula for gravitational potential energy, which is equal to mgh (mass x gravity x height). Close to Earth, gravity is approximately 9.8 newtons/meter.
What is the potiential energy of the 85 kg rock?
For every meter it's raised, it gains 833 more joules of gravitational potential energy.
What are some factors that affect potential energy?
(Gravitational) potential energy = mgh (mass x gravity x height). Those are the three factors. In standard units (SI), mass is given in kg., gravity is around 9.8 meter / second square, and the height should be given in meters.
Can an object have no either potential energy and kinetic energy?
Yes. Potential energy is energy that has not yet been released. Kinetic energy is energy or an object already in motion.Think of a ball 1 mile up in the air that begins to fall. After it has fallen 10 feet, releasing some, but not all of its potential energy, it has built up some kenetic energy as well from the motion of falling 10 feet, but still has 5270 feet worth of potential energy to go. What happens as the ball falls is that it gradually changes all of its potential energy into kinetic energy.co
A ball of weight 10N is dropped freely from rest at a height of 4 m.what is its total mechanical energy after it has traveled 1 meter?
If you are ignoring energy lost due to friction, the total mechanical energy will be the same after it has traveled 1 meter as when it was dropped. This means the easiest way to solve the problem is to find the mechanical energy at the beginning, when the ball is at rest and all of its mechanical energy is gravitational potential energy. Gravitational potential energy equals mass*g*height. Since mass*g equals weight, we can just multiply 10N by 4m, making the total mechanical energy 40J.After it has traveled 1 meter, some of the gravitational potential energy has been converted into kinetic energy. The gravitational potential energy is just the weight of 10N multiplied by the height of 3m, or 30J. To find the kinetic energy, we need to find velocity2, which equals 2 times acceleration (g) times displacement (1m) when the initial velocity is 0. We also need the mass, which is weight (10N) divided by g. Kinetic energy equals (1/2)*mass*velocity2, so we get (1/2)*10N÷g*2*g*1m, which equals 10J, so the total mechanical energy is still 40J.
What is the definition of pontential energy?
Potential energy takes many different definitions, but the most common is due to gravity. Say move a book from the floor to a shelf that is one meter above the ground. The book has a mass of 2 kilograms. While the book is on the floor, it has zero potential energy. Since potential energy is defined as the height times the mass times the gravitational constant, and height is equal to zero at that point, there is no potential energy. But when it is moved to one meter high, the math goes as follows: 1 meter X 2 kilograms X 9.8 meters per second squared(The gravitaional Constant) = 19.6 Joules(The unit of potential energy).
Does height effect potentail energy?
yes height effects potentail energy because if you have a meter stick and a ramp at 50 centemeters with a block at the bottom then roll a ball down the ramp the block at the bottom will go pretty long but if you put the ramp higher the block will go longer
What is the si unit for potential energy difference?
Potential energy is measure in Joules (J). A Joule is a Newton*meter (N*m)
