Kinematics

The "per hour" bit is the same, so the question is equivalent to 65 miles in kilometres.

65 miles = 104.6 km so 65mph = 104.6 kmph.

82 kilometres = 82,000 metres

1 hour = 3,600 seconds

82,000 / 3,600 = 22.78 metres per second

No, the average velocity is calculated as the total displacement divided by the total time taken to travel that distance. It is not simply the mean of the initial and final velocities.

Kinetic energy is determined by the formula, Ek = mv2/2, and a large meteor has more mass and velocity than a baseball. Mass matters, but the velocity gets squared.

is More Information:

Two factors that give any meteorite higher kinetic energy than a batted baseball, are their comparative masses and velocities. A baseball may weigh about 9 oz and travels a little over a hundred miles an hour off the bat. Even a meteorite of small mass has more kinetic energy than that because of its high velocity (maybe about 25,000 miles an hour, or more). A large meteorite would have high velocity also, but given large mass, it would have extremely high kinetic energy.

100 kilometers per hour (kph) is much faster.

I don't know about the world. But my son Seth plays baseball and the fastest kid in his league is Nathan Payne he can fly.

285 kph = 177.1 mph

600 knots is about 690.5 mph.

Formula: miles x 1.609 = km

Gas molecules with higher kinetic energy tend to exert more force on their container walls, increasing the pressure. Conversely, gas molecules with lower kinetic energy exert less force and thus lower the pressure. So, gas molecules with more kinetic energy do not lower pressure; they increase it.

There are 1000 meters in a kilometer(1000 m) / (1 km). There are 3600 seconds in an hour, so (1 hr) / (3600 s). you can just multiply (1 km / hr)*[(1000 m) / (1 km)]*[(1 hr) / (3600 s)] to get 0.28 m/s.

I guess fps stands for feet per second. Divide that number by whatever the number of feet there is in a mile, to convert to miles per second. Then multiply the result by 3600 to convert from "per second" to "per hour".

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.

Jb..

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.

Jb..

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.

A skateboard rolling across the street A hockey puck sliding across the ice

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.
