Kinematics

Potential energy is related to an object's height, specifically gravitational potential energy. This type of energy increases with an object's height above the ground and is a measure of the work that can be done by gravity as the object falls.

A byte is 8 bits. They can represent all of the ASCII characters and any value between 0 and 255. It could be both. It just represents a value.

An Idler Gear is usually used to maintain a stable tension on a belt or chain, OR it is used to redirect the position of the belt or chain. An idler gear transmits no power to or from the belt or chain.

The average speed is calculated by dividing the total distance by the total time. In this case, the average speed would be 16 km/hour since 24 km divided by 1.5 hours (90 minutes converted to hours) equals 16 km/hour.

55 kph = 34.2 mph

Kinetic energy is the energy an object possesses due to its motion. It is calculated as one-half of an object's mass multiplied by its velocity squared (KE = 0.5 * m * v^2). The faster an object is moving or the more massive it is, the greater its kinetic energy.

The General Dynamics F-111F "Aardvark" has a maximum speed of Mach 2.5 (1,650 mph, 2,655 km/h)

I think all rotational motion are periodic. There is not possible of nonperiodic

An ostrich can run at speeds up to 45 miles per hour (72 kilometers per hour), which makes it the fastest bird on land.

It doubles. Momentum (p) is the product of velocity (v) and mass (m). For a given mass, if you double the velocity, you'll double the momentum. Velocity and momentum are said to be directly proportional. p = m x v

66.7 m/s2

Hang time is the amount of time an object remains in the air after being propelled upwards. It is often used in sports like basketball to describe how long a player stays in the air during a jump before reaching the peak of their jump and descending back to the ground.

To lift 100 kg at a distance of 100 cm from the fulcrum with an effort 100 cm from the fulcrum, you would need to apply a force of 100 kg in the opposite direction at a distance of 100 cm from the fulcrum. This is because the lever equation states that force x distance on one side of the fulcrum must equal force x distance on the other side.

no that is not true everybody knows that when something is moving it has k.e , wich means that it has kinetic energy and when is not moving its p.e potential energy so I dont see how acar has the less k.e when its moving the answers is it has the less p.e

The speed of a 90 mph pitch as it crosses the plate would likely be a little less than 90 mph, as there is air resistance and friction that can slow the pitch down slightly.

There is a very real possibility that hitting the head at 15 mph will have the same impact or worse as being hit with a sledge hammer. The outcome of this experiment truly depends on the size and force of the object hitting the head.

218 kph = 136.25mph

A body is moving at 218 kilometers per hour.

To find out how many miles will it move in the same amount of time, we will need to convert killometers into miles.

1 km = 1.6 miles

therefore 218 km = 218/1.6 miles = 136.25 miles.

Once a particular reference frame is established, whenever friction is observed between two objects, one of the objects speeds up as a result of the frictional force and one of the objects slows down with respect to that reference frame. Imagine a wooden block at rest on an ideal, frictionless surface. If you were to place something on top of the block and drag it across the surface of the block, the friction that resulted would cause the block to move. Since it started at rest and it ended in motion, it sped up as a result of a frictional force. In this example, since the non-frictional forces (the weight of the something you dragged along the top surface of the block) can only be exerted in the direction of the normal, the only force that is left that could possibly cause any movement of the block is due to friction.

115 km per hour = 71.5 mph (to 1 dp)

the bag of apples ........ the weights of the apples are acting in same direction so it is an example of parallel forces

40 miles per hour is approximately equal to 64.4 kilometers per hour.

Well ive gota 1998 that is stock that does around 109 ahah mph not kph

Running 100 meters in 12.5 seconds is equivalent to running at a speed of 22.4 miles per hour.

a = w2r = v2/r

where

a is acceleration

w is angular velocity

r is radius of orbit

v is velocity.

Both, if you refer to a flowing stream. The topographic elevation of the streambed above the base level toward which it leads (e.g., sea level) is indicative of the potential energy of the water in the river. (Another kind of potential energy is proportional to the water depth above the streambed.) The river's kinetic energy is proportional to the square of its current velocity and to the mass of moving water. Remember KE = (m v^2)/2 from physics?

If the river ceases to flow, for example enters a lake or impoundment, its kinetic energy will decrease to zero. Yet because of potential energy, its water may still have considerable energy.
