yes but its the citrus and acids in fruits that can produce electricity by sticking electrodes inside of the (try galvanized nails and copper strips)
What is the formula for angular momentum?
The formula for angular momentum is L = r x p, where L is the angular momentum, r is the distance vector from the axis of rotation to the point of interest, and p is the linear momentum. This formula describes the rotational motion of an object around a fixed axis.
Kinect energy refers to the energy generated while using the Microsoft Kinect sensor, which is a motion-sensing input device for the Xbox gaming console. The Kinect sensor captures movements and translates them into controls for games or other applications, converting physical movements into digital inputs.
Why aeroplanes and cars have streamline shape?
Aeroplanes and cars have a streamlined shape because it reduces the amount of air drag / air resistance, thus allowing less amounts of energy to be wasted. For example, it cars were to be designed like trucks, this would increase friction, slowing the object down. Take the example of sports cars. They are streamlined so that when it flows through the air, the car can travel smoothly, not clumsly-like movements. Trying experimenting this with a parachute and you'll see why.
This is a quantity that has both size and direction?
Such a quantity is called a vector.
A shining example is velocity itself.
velocity is the rate of change of displacement- the distance moved by particle in a specified direction.
Since velocity = displacement/time taken = vector/scalar, Velocity thus has both a direction and a magnitude (magnitude = speed of particle)
Another examples include quantities such as Force, acceleration, displacement
Kinetic energy is the energy possessed by a body because of its motion. The formula for kinetic energy is KE = 1/2mv2, where m is mass in kg and v is velocity in m/s.
How do you find the amount of mechanical energy lost when colliding with a floor?
To find the amount of mechanical energy lost when colliding with a floor, you can calculate the difference in kinetic energy before and after the collision. Subtract the final kinetic energy (which would be zero if the object comes to a stop) from the initial kinetic energy to determine the mechanical energy lost during the collision.
How is your kinetic energy related to your speed?
How is your kinetic energy related to your speed?
Kinetic Energy is proportional to the square of the velocity. If the velocity is doubled, the KE is 4 times as much.
I don't remember ever seeing the KE formula derived. I derived it from motion and work equations.
1) Work input = Force * distance
Work input causes increase in KE
Force * distance = increase in KE
If the object is at rest initially,
2) Work input = Force * distance = KE
3) Force * distance = KE
Force = mass * acceleration
4) F = m*a
Acceleration = (Vf - Vi) ÷ time, Vi = 0,Vf = V
5) a = V ÷ t
Substituting V ÷ t for a
6) F = m*( V ÷ t)
Distance = Average velocity * time
7) Average velocity = (Vi + Vf) ÷ 2, Vi = initial velocity, Vf =final velocity
If the object is at rest initially, Vi = 0, Vf is the velocity at specific time.
8) Average velocity = V ÷ 2
9) Distance = (V ÷ 2) * time
10)Force * distance = KE
……………….From Eq.#6………..From Eq#9
11) F = m*( V ÷ t)…… Distance = (V ÷ 2) * t
12)Force * distance = m*( V ÷ t) * (V ÷ 2) * t
Be careful of numerators and denominators. What is divided by what!
13)Force * distance = (M * V^2) Substituting from Eq #2 reversed, Work input = Force * distance
14)Work input = (M * V^2) ÷ 2
15) Kinetic Energy = ½ * Mass velocity^2
16)Work input = ½ * Mass velocity^2
There it is, the Kinetic energy formula derived from work and motion equations.
What is describing motion using words instead of numbers is called what kind of kinematics?
Describing motion using words instead of numbers is called qualitative kinematics. This approach focuses on the characteristics of motion such as speed, direction, and changes in motion without quantifying them numerically.
What is potential energy that is directly related to how high an object is?
Gravitational potential energy is directly related to an object's height above a reference point, such as the ground. It is the energy stored in an object due to its position in a gravitational field. The higher an object is lifted, the greater its gravitational potential energy.
Having four-wheel drive can help with traction on icy roads, but it won't necessarily make the car faster around corners. The key to driving safely on icy roads is to reduce speed and drive cautiously regardless of the drivetrain. It's always important to adjust your driving according to the road conditions to avoid slipping.
Is 1 mile per hour equal to 6.2 kilometers per hour?
No. One mile per hour is 1.609 kilometers per hour.
What is the word for a person being experimented on?
The word for a person being experimented on is a "subject."
Phyz (Dax Phyz), is a public domain, 2D computer graphics physics engine with built-in editor and DirectX graphics and sound. In contrast to most other real-time physics engines, it is vertex based and stochastic. It's integrator is based on a SIMD-enabled assembly version of the Mersenne Twister random number generator, instead of traditional LCP or iterative methods, allowing simulation of large numbers of micro objects with Brownian motion and macro effects such as object resonance and deformation.
What is one way to increase the momentum of an object?
Momentum is of two kind. One is linear momentum and the other is angular momentum.
Linear momentum is defined as the product of the mass and the velocity. Hence a vector quantity.
To change the momentum of a given body with its mass constant, its velocity is to be changed. Velocity change could be made by changing its magnitude or direction or both.
Angular momentum is the product of moment of inertial and the angular velocity. Same manner, angular momentum is also a vector quantity as angular velocity is a vector quantity.
Most of us think that moment of inertia of a body about any prescribed axis is also a vector quantity. It is totally wrong as far as my approach is concerned. Moment of inertia is a scalar quantity.
So to change the momentum, some force can be applied by allowing a moving body to collide with.
Angular momentum can be changed by applying torque on it. Torque colloquially saying is a turning force. Moment of effective force about an axis is termed as torque.
How fast is a 4kg bird flying if it has 8 joules of kinetic energy?

What is the energy attributed to an object by virtue of its motion known as?
The energy attributed to an object by virtue of its motion is known as kinetic energy. It is dependent on the object's mass and velocity, with the formula being KE = 0.5 * mass * velocity^2.
What is the mathematical formula for how far a baseball has been hit?
There is an equation called the Range equation that can be used here. This equation only applies when the starting altitude and ending altitude are the same for the object. R = v2 sin(2 Theta)/g v is the initial velocity of the ball, theta is the launch angle, and g is the gravitational constant(9.8 meters per second squared or 32.2 feet per second squared depending on which system you wish to use). R is the distance the ball is hit.
Does thunder have kinetic energy?
It has kinetic energy because it is moving. Just because it is in the air doesn't mean that it can't have kinetic energy.
Describe the momentum of objects at rest?
Measured in the frame of reference in which the object is at rest; zero since momentum is mass times velocity. Note that momentum is zero but inertia is not.
A car has a kinetic energy of 2000 joules If the speed doubles its kinetic energy will?
It will be 8000 joules. ( if the velocity of a car has been doubled, the KE will be quadrupled. Because the KE is directly proportional to the velocity squared.)
KE= 1/2 m v2

We have to assume that the 785 km/hr is the speed measured by an observer on the ground, NOT the closing speed. The closing speed is (785 x 2) = 1,570 km/hr. If the impending catastrophe first attracts their attention when they are 11 km apart, then the distance between them at that instant represents 11/1570 = 0.007 of an hour = 25.22 seconds (rounded)
