Kinematics

Yes, energy can exist as both potential energy and kinetic energy. Potential energy is stored energy that results from an object's position or condition, while kinetic energy is the energy of motion. As an object moves, potential energy can be converted into kinetic energy, and vice versa, following the law of conservation of energy.

At the highest point it's potential energy, which is then completely converted to kinetic energy as the swing travels through its lowest point at maximum speed. With an ideal swing (no friction) the sum of potential and kinetic energy stays constant (it is 'conserved'). In practice it dies away as the swing slows down, but Conservation of Energy is an important principle in science.

The reasons are the same as they are for any similar oscillatory system. It is largely because energy is dissipated as heat wherever there is friction: at the ends of the strings and where the balls collide. Hence the total amount of energy within the system falls until the oscillation is no more. Wherever there are resistive forces, there can be no perpetual motion without violating the Conservation of Energy principle.

No, Potential Energy is the energy of an object that has the potential to move while kinetic energy is the energy of an object at motion.

Potential energy is defined by Mass * Gravity(9.81ms-2) * height(In meters)

Kinetic energy is defined by (1/2)*Mass*Velocity2

No, "miles per hour" is not hyphenated. It is written as three separate words.

The weight of a Nickel is 5 grams or 0.005 KG

For example

If a Nickel is dropped from a height of 1 metre (NEAR EARTH SURFACE GRAVITY)

the velocity just before impact is 4.427188724235731 metres per second

if the mass of the object is 0.005 Kg

then the kinetic energy of the object just before impact is 0.049 J

This is obviously directly proportional to the air flow and this example assumes that air friction is negligible.

while we are here lets calculate the impact force of the falling object..

now where's my beer.

the change in kinetic energy of the nickel is equal to the net work chivied on the object

therefore

the average impact force X distance traveled equals the change in kinetic energy

therefore the distance traveled is 0.02 metres

but this is obviously directly proportional to the density of the surface that it falls into, for this example i have used sand.

The aircraft carrier is much heavier than the falling nickel, which means it has more mass. Since kinetic energy is directly proportional to an object's mass, the aircraft carrier will have a greater kinetic energy compared to the nickel despite both having the same velocity just before impact.

One meter per second is a unit of speed that describes the rate at which an object is moving. It means that the object is traveling a distance of one meter every second. This unit is commonly used to measure the speed of objects in physics and everyday life.

kinetic energy is 1/2mv^2, our velocity is 20 m/s , our mass is 2000 kg. Plugging it in you get 1/2 (2000) (400) = 1000 * 400 = 400000 joules

An object with the greatest amount of kinetic energy would be one that is both heavy and moving at a high speed. For example, a speeding bullet or a fast-moving train would carry a significant amount of kinetic energy due to their mass and velocity.

Yes, it is true. The average kinetic energy of gas particles is directly proportional to their temperature according to the kinetic theory of gases. So, when the temperature doubles from 100 to 200, the average kinetic energy of the steam particles also doubles.

The total energy of an object is the sum of its kinetic energy (energy of motion) and its potential energy (energy of position). The combined total of kinetic and potential energy is known as the mechanical energy of the object.

The main energy wasted while riding a bike is in overcoming aerodynamic drag, rolling resistance, and inefficient pedaling technique. These factors can lead to energy losses in the form of heat and vibration. Improving bike efficiency, maintaining proper tire pressure, and focusing on a smooth and steady pedaling motion can help minimize energy wastage.

You must maintain a pace of at least 8.1 miles per hour for 2600 meters.

Kinetic energy is proportional to the square of the velocity, so increasing speed even slightly results in a larger change in kinetic energy. This relationship means that a small increase in speed has a disproportionate impact on the kinetic energy of an object.

To find the average speed of an object over a given time, you divide the total distance traveled by the object by the total time taken to cover that distance. Mathematically, average speed = total distance / total time.

Scalar quantity has only magnitude , but no direction while vector quantity has both magnitude and direction.You can understand it by comparing speed and velocity.Velocity has magnitude of speed in a particular direction (or say displacement/time take) while speed only defines the rate of distance covered (no direction).

If you are still unable to get your answer for your question then please, elaborate or give some description of extension.

1mi = 1.61km

190mi/h x 1.61km/mi = 306km/h

Could be dirty fuel injectors, or perhaps water or other contamination in the gasoline.

I suppose it could also be that you have run out of lubricating oil, but in that case, the engine would weld itself together, and it would never run, again.

The total momentum before the collision is the same as the total momentum after the collision. This is known as "conservation of momentum".

To convert 10 minutes and 20 seconds to hours, first convert 20 seconds to minutes (20/60 = 0.33 min). Then add this to the 10 minutes to get a total of 10.33 minutes for the mile. Finally, divide 60 (minutes in an hour) by 10.33 to get approximately 5.8 mph.

Mass is directly proportional to the amount of kinetic energy an object posses according to this formula.

Ek= 1/2mv2.

There are two factors, which can alter the amount of kinetic energy.

1. The velocity of an object, how much momentum does the object carry.

2. The mass, small or big.

if an object with mass of 5kg travelling at 7m/s has an overall kinetic energy of 123j. directly if an object weighing twice to have the same kinetic energy, its mass should be 4.959kg.

you can get this using v2=Ek/0.5m.

The potential energy given to the hammer is calculated using the equation PE = mgh, where m is the mass (50.0 kg), g is the acceleration due to gravity (9.8 m/s^2), and h is the height (4.00 m). Plugging in the values, PE = 50.0 kg * 9.8 m/s^2 * 4.00 m = 1960 J.

26 knots is approximately equal to 30 miles per hour.
