Kinematics

When the bob of the pendulum while moving stops at one, its Kinetic energy changes completely into potential energy and when it starts its motion again, the potential energy changes to the kinetic energy

Speed is a scalar quantity (direction does not matter) and velocity is a vector quantity) ie velocity means speed in a specific direction.

If you are changing direction (turning) in a car, your speed is the same, while your velocity changes.

The potential energy of any object is measured using the equation U = mass * gravity * height to the object. Thusly:

U = m*G*h

U = 17.8 kg * 9.81 m/s2 * 854 m

U = 149 123.8 kg m2/s2 or Joules

The terminal velocity of a falling human (including a baby) at sea level is approximately 120 mph (193 km/h). At this speed, air resistance balances out the force of gravity, leading to a constant velocity. It is also worth noting that other factors, such as air pressure and body position, can influence the terminal velocity.

Shooters aim slightly above the target to compensate for the downward trajectory of the bullet due to gravity. This technique is known as adjusting for bullet drop and ensures that the bullet will hit the target accurately at longer distances.

The X-43, an experimental unmanned aircraft, set a speed record of approximately Mach 9.6, or nearly 7,000 mph, during a test flight in 2004. This makes it one of the fastest aircraft ever built.

The formula for potential energy, (mgh), comes from the equation (PE = mgh), where (PE) represents potential energy, (m) is mass, (g) is acceleration due to gravity, and (h) is height. This formula represents the energy an object possesses due to its position relative to a reference point.

As the plane hits the deck, its kinetic energy is 1/2 (its mass) x (its speed)2,

so that's the amount of energy that has to go somewhere in order to bring

the plane to a complete stop where its kinetic energy is zero.

My guess at the moment is that the energy must be dissipated in one humongous

shock-absorber at each end of the cable. Springs don't dissipate the energy ...

they only store it, and then it still has to go somewhere. Shocks dissipate it.

315 kph = 195.7 mph

The top speed of a Jigster 1000 motorcycle is around 160-170 miles per hour, depending on various factors such as rider weight, road conditions, and maintenance of the bike.

Since kintetic energy is the energy of motion it depends on the two. mass affects inertia and inertia applies to kinetic energy. and speed is applied because the faster it going the more kinetic energy the object has.

6 km/h is equivalent to approximately 3.73 mph.

20 km/h is 12.4274 mph

To change an object's velocity, you can apply a force in the direction you want it to accelerate. This force can be produced by pushing, pulling, or using any other method of applying force to the object. Additionally, altering the mass of the object or the direction of the force can also change its velocity.

This is done in order to get unbalanced force act on the pendulum. A torque will act due to gravitation of the earth and the tension in the string as they then act at different points and opposite direction on the pendulum. Have the forces act at the same point, the formation of torque would have been ruled out and the pendulum would not swing.

The acceleration from 25kmh to 30kmh is greater.

Acceleration is the rate change in velocity with respect to time (dv/dt). Going from an initial velocity at one point in time to a final velocity at a later point in time, the average acceleration is given by (vf - vi)/(tf -ti), the change in velocity divided by the duration of acceleration. Since going from 25kmh to 30kmh is a change in velocity of 5kmh and going from 96kmh to 100kmh is a change in velocity of 4kmh, and the duration of each is the same, 25 to 30 is the greater acceleration.

We suspect that you're also given a line on the graph. If so, then the initial speed

is the slope of the line at the initial position. To get the real slope of the line, you

need to know the scales of the axes. If the scales aren't the same, then the real

slope of the line isn't what it looks like, and has to be calculated by measuring its

progress along both axes just after the initial position.

In this question, we would use the equation

K = 1/2mv^2

we know:

mass (m) = 6 kg

initial velocity (v) = 2 m/s

therefore, K = 1/2(6)(2^2)

K= 12 Joules (J)

320 Km/h = 198.838782 M/h

800 feet in 2 minutes 40 seconds equates to 3.41 miles per hour.

Fines for speeding in a work zone can vary depending on the state and local laws. It's best to check with the specific jurisdiction where the violation occurred to determine the exact fine amount for going 62 mph in a work zone. Note that fines for speeding in work zones are often higher than regular speeding fines to promote safety for road workers.

The change in velocity over time is known as acceleration. It measures how quickly an object's velocity is changing, either speeding up, slowing down, or changing direction. Acceleration is calculated by dividing the change in velocity by the time taken for that change to occur.

The Rocket locomotive, designed by George Stephenson, achieved a top speed of around 30 miles per hour during its initial trials without pulling any load. This was an impressive speed for the time, demonstrating the effectiveness of its design and engineering.

The kinetic energy of the dog can be calculated using the formula: KE = 0.5 * m * v^2, where m is the mass of the dog (10 kg) and v is the velocity (5 m/s). Plugging in the values, KE = 0.5 * 10 kg * (5 m/s)^2 = 125 Joules.
