Kinematics

23 miles per hour is approximately the fastest a human has run.

Yes, a roller coaster car has potential energy when it is at the top of a hill, due to its height and gravity. As the car descends, this potential energy is converted into kinetic energy as it gains speed.

Impossible. Any moving object would become infinitely faster, and gravity would be infinitely stronger. Friction keeps the tectonic plates from moving any faster. This would be impossible to imagine, even for the most scientific minds.

The speed of an object does not change if only its mass is doubled. The speed of an object is determined by its velocity, which is independent of its mass. However, doubling the mass of an object will affect its momentum and kinetic energy.

This is a simple little problem once you get your mind to it. Let the mass be M kg and the max height of the swing be H meters (that is the height of the mass above its lowest point, not the length of the swing).

Max velocity = 4 m/s, so max kinetic energy (KE) = 1/2 x M x 42 = 8M

We are assuming the potential energy (PE) at max height = kinetic energy at lowest point, ie no losses due to friction. Max PE = M x G x H where G = the gravitational constant.

So we have PE = KE = M x G x H = 8 x M, M cancels out and H = 8/G. Then substituting back for H, max PE = 224 = M x G x 8/G, G cancels out and M = 224/8 = 28 kg.

The object with the greatest gravitational potential energy in this scenario is the trophy cup, given that potential energy is directly proportional to both the mass and the height of an object. In this case, the trophy cup has the highest mass (6 kg) and height (0.5 m) combination, leading to the greatest gravitational potential energy.

Kinetic energy is extra energy resultant of motion. So, a moving vehicle has kinetic energy.

The top speed of a Shogun Pro will depend on various factors including engine displacement, gear ratios, tire size, and other modifications. It is recommended to consult a motorcycle mechanic or refer to the owner's manual for specific information on sprocket combinations that can help achieve the desired top speed.

After 12 seconds, a car traveling at 87 miles per hour would have traveled approximately 1,520 feet. This can be calculated by first converting 87 miles per hour to feet per second, which is about 128 feet per second. Multiplying this by the number of seconds gives the distance traveled.

As a pendulum swings, energy is converted between potential energy (at its highest points) and kinetic energy (at its lowest points). At the highest point, the pendulum possesses maximum potential energy due to its height above the ground. As it swings down, this potential energy is converted into kinetic energy, reaching its maximum speed at the lowest point. The energy conversions during the swinging of a pendulum demonstrate the principle of conservation of energy, where the total mechanical energy (the sum of potential and kinetic energy) remains constant throughout the motion, disregarding any energy losses due to friction.

The kinetic energy of the fan blade will decrease to one ninth of its original value because kinetic energy is proportional to the square of the angular velocity. So, if the angular velocity is reduced to one third, the kinetic energy will decrease to (1/3)^2 = 1/9 of its original value.

Velocity change can result in changes in an object's speed and/or direction of motion. This change in velocity can be caused by forces such as acceleration, deceleration, or changes in direction, which can affect the object's kinetic energy and momentum.

Increasing the mass decreases the acceleration.

Newton's Second Law: F = ma (Force = mass x acceleration) --> a = F/m, meaning that the relationship between the acceleration and the mass is inversely proportional.

Mass is a scalar quantity because it doesn't have direction.

Acceleration is a vector quantity because it has both magnitude and direction.

As strange as it may seem at first, the ball is actually moving towards the center, its just that when the centripetal force pulls the ball towards the center, the objects preexisting speed moves it to another spot on the circle, stopping it from actually spiraling inwards.

One way to visualize this is to imagine that you throw a ball. Under normal circustance, when you throw the ball, it will go forward for a little bit but it will eventually be pulled down by gravity and hit the ground. Now, imagine that you could throw the ball so fast that by the time it falls 10 feet, it has gone far enough out form the Earth that there is another 10 feet to go before it reaches the ground. Thus, even though the ball is getting pulled towards the Earth, its falling as fast as its moving.

Its this combination of falling and moving that actually creates the circular motion. If the falling is faster than the moving, the object will just eventually spiral into whatever is pulling on it. Alternatively, if the moving is faster than the pulling, there will be an overall hyperbolic path, as the object gets close to the source of the pul but then shoots away.

A body moving at a uniform speed may have a uniform velocity, or its velocity could be changing. How could that be? Let's look. The difference between speed and velocity is that velocity is speed with a direction vector associated with it. If a car is going from, say, Cheyenne, Wyoming to the Nebraska state line at a steady speed of 70 miles per hour, its velocity is 70 miles per hour east. Simple and easy. Uniform speed equals uniform velocity. (Yes, I-80 isn't perfectly straight there. Let's not split hairs.) But a car moving around a circular track at a uniform speed is constantly changing direction. Its speed is constant, but its velocity is changing every moment because the directionit is going is changing. Speed is uniform, but velocity isn't. As asked, uniform speed is a uniform distance per unit of time. And this will yield a uniform distance per unit of time in its velocity, but the direction vector may be uniform or it may be changing each moment, as illustrated.

Arthur Compton demonstrated that photons transfer momentum during collisions with matter in his Compton scattering experiments. This phenomenon provided evidence for the particle-like nature of light and helped lay the foundations for the field of quantum mechanics.

Central petal force is the force exerted on the central petal of a wind turbine blade due to aerodynamic loads. It plays a crucial role in the structural design and performance of wind turbine blades, as it affects the overall efficiency and reliability of the turbine. Properly understanding and managing central petal force is essential for optimizing wind turbine operation.

The missing mass in the nucleus, known as mass defect, is converted into energy according to E=mc^2, where E is energy, m is mass, and c is the speed of light. This conversion is responsible for the energy released in nuclear reactions such as fission and fusion.

To measure smaller object use ruler or measuring tape.

Or

For long paths use laser distance measurer

Or

For further long distances use Side road millage stones

Or

For Still long distances JUST USE google earth :p

Hope it helped

Energy balls are not a real physical phenomenon in the scientific sense. The term "energy balls" is often used in a metaphorical or pseudoscientific context to refer to certain spiritual or metaphysical practices.

roughly 31 mph. the formula is (KM * 0.62)

Her final speed is 14.5 m/s.

The kinematics equation v = at + v0 will be useful here. Note that t is the time measured in seconds, a is the acceleration, v0 is the initial velocity, and v is the velocity after t seconds (the final velocity).

We are given that v0 = 10 m/s, a = 0.500 m/s2, and t = 9 s.

Using the above kinematics equation we get v = (0.500 m/s2)(9 s) + 10 m/s = 14.5 m/s.

Since speed = |velocity|, then her final speed = |14.5 m/s| = 14.5 m/s.
