Kinematics

In positive acceleration, the final velocity is greater than the initial velocity. This is because acceleration is the rate of change of velocity, so as time progresses, the velocity increases due to the acceleration.

Yes, it is possible. For example, if a particle moves back and forth between two points with different speeds, such that the time spent at each point is unequal, the average speed would not be zero even though the particle's speed is zero at each point.

A kicked football has, of course, kinetic energy. As it moves up, its vertical movement provides potential energy. Until it goes up to its maximum displacement from the ground, its potential energy is at 100% while the kinetic energy doesn't exist. As the football moves back down, its potential energy is decreasing, but kinetic energy is increasing because there's movement in the football

1 mile = 1.6 km

Convert miles to kilometers by multiplying miles x 1.6km/mi.

30mi x 1.6km/mi = 48km

30mi/h = 48km/h

30mi/h is less than 60km/h.

Radiation is a form of energy that includes both kinetic and electromagnetic energy. Kinetic energy refers to the energy of moving particles in radiation, such as in the case of alpha or beta particles. Electromagnetic energy refers to the energy carried by waves, like gamma rays.

The average kinetic energy of particles in a substance is directly related to its temperature. Understanding this average kinetic energy helps us predict how the substance will behave in various conditions, such as changes in temperature or phase transitions. This knowledge is crucial in fields like thermodynamics and materials science.

No, a hammer held above a nail has potential energy due to its position relative to the nail. Potential energy is energy that an object has due to its position or state, whereas kinetic energy is energy of motion.

20 km per hour is approximately equal to 12.4 miles per hour.

Gaining kinetic energy 'E' amounts to saying that the momentum of an object increases.

E = p^2 / 2m

where p is momentum and m is mass. (Momentum is just mass times speed.)

So, to increase the speed the kinetic energy has to change. In other words, if you set the kinetic energy to any value you like and keep it constant, there won't be a speed up.

What is the change in kinetic energy? You can just as well ask what is the change in momentum. Physicists have chosen the latter question and call the change in momentum 'the force'.

F = dp / dt

where F is force and d/dt means derivation with respect to time.

It is the pushing force acting on objects that makes them gain speed. Kinetic energy is usually something that you calculate at the end when you have found out what the forces in your problem are and what the momentum is as a function of time.

5 km per second = 18,000 km/h or 11,184.7 miles per hour.

100 kilometers per hour equates to 62.14 MPH

An electron can reach zero velocity by experiencing a slowing force, such as friction, that opposes its motion. Alternatively, if an equal and opposite force acts on the electron to stop its movement, it can also reach zero velocity.

407 kmh = 252.9 mph

Base speed typically refers to the starting speed of a character or object in a video game or tabletop role-playing game. It is often used as a reference point for calculating movement distances or determining turn order. Base speed can vary depending on the specific game rules or character statistics.

The kinetic energy of the particle increases as the speed increases, following the equation ( KE = \frac{1}{2} mv^2 ) where ( KE ) is the kinetic energy, ( m ) is the mass of the particle, and ( v ) is the speed of the particle. The energy of the particle is converted to kinetic energy as its speed increases.

The internal energy of a material includes both the kinetic and potential energy of particles. Kinetic energy is associated with the motion of particles, while potential energy is associated with the interactions between particles, such as chemical bonds or intermolecular forces.

The formula for working out Potential enery is:

PE = mgh - where g equals to the acceleration due to gravity (which is 10 newtons)

- mass should be in Kg's

- and height in meters

- final answer should be in Joules (J)

Therefore substitute it in :-)

Pe = (500g = 0.5kg) x (10N or more exact 9.8N) x (2 meters)

Pe = 10 Joules of potential energy with a object weighing 500g (or 0.5 kg) and from a height of 2 meters

To calculate the velocity of a moving object, you divide the change in its position by the time it took for that change to occur. The formula for velocity is velocity equals displacement divided by time taken (v = d/t). The resulting value will have units of distance traveled per unit of time (e.g. meters per second).

Yes, 45 km/h is greater than 40 mph. To compare the two units, you should convert them to a common unit of measurement (such as km/h) for an accurate comparison.

Distance travelled from a velocity / time graph can be calculated from area under graph, say area under (v/t) graph from 0 - 1 seconds = distance travelled after 1 second, then do 0 - 2 seconds, 0 - 3 etc for set of data for distance / time graph

Kinetic energy is dependent on which point you are talking about. When it is about to be dropped, kinetic energy is zero. When it reaches almost hits the ground, there is maximum kinetic energy.

300 feet per second = 204.5 mph

The change of energy as it moves between kinetic and potential energy is called mechanical energy. This occurs in systems where the total mechanical energy (kinetic + potential) remains constant, such as in the case of an object in free fall or a swinging pendulum.

An upward sloping diagonal line on a velocity vs. time graph represents constant acceleration. The steeper the slope, the greater the acceleration.
