What is the Ek - kinetic energy - of a soccer ball which has a mass of 1 kg and is kicked at a velocity of 10m per s?

Since Ek (kinetic energy) is
Ek = 1/2 m v²
0.5 x 1 kg x (10m/s)² = 50 kg∙m/s² = 50 J
J is Joules

What are some objects that have kinetic energy?
Kinetic energy is the energy an object has due to its mass and its velocity. Kinetic energy is calculated with the equation: Ek = ½ mv² Since kinetic energy is proportional to mass and velocity, any object moving very slowly has a small amount of kinetic energy. Also, any very small object normally has a small amount of kinetic energy. For example, a soccer ball rolling down a hill might have a relatively small amount of kinetic energy.
How does kenetic and potential energy affect soccer in general?
In soccer, you have a soccer ball. The ball has potential energy. When you kick the ball, the potential becomes kinetic energy and the ball moves. However, your foot has potential energy as well (all matter has potential energy because all matter has the potential to move). When you kick with your foot that potential energy becomes kinetic energy. When the soccer ball is on the ground it actually has no potential energy because potential energy is only associated with height. When the ball is kicked however the kinetic energy from the player is passed on to the ball. That kinetic energy makes the ball move. If the ball is kicked into the air then the kinetic energy is passed on and some of that kinetic energy transforms into potential energy and kinetic.

Why are you sleepy in the afternoon?
if you're energy is low your always tired, the normal sleeping hour is 1-8

What is the velocity of a football when it is hit?
The record speed for a soccer ball to have been kicked by a pro soccer player is 110 mph.
What science energy do you give to a soccer ball when you kick it?
Kinetic Energy
When a soccer ball is kicked the action and reaction forces do not cancel each other out because?
when a soccer ball is kicked, there is a transfer of energy from your leg to the ball. since the ball is elastic, it coverts the kinetic energy from your leg into potential elastic energy in the for of deformation of the ball. the ball then snaps back to its elastic equilibrium converting the energy back to kinetic energy. also, your momentum is being transferred to the ball, giving it a direction since momentum is a vector. due to these conversions of energy and momentum, the ball is sent off your foot in the direction you kicked it with the same speed you kicked it with.
A soccer ball rolling toward a goal potential or kinetic energy?
Your foot exerts a force on the ball, causing it to accelerate, and the ball exerts the same force on your foot, which does not cause you to accelerate because that force is transmitted through you into the planet Earth that you are standing on, which is so massive that it is not noticeably affected.
Do a soccer ball have energy?
Yes. Air pressure in the ball. Kinetic energy if moving.
What is the velocity of a soccer ball kicked into the goal that is 28 meters away and it arrives in 1.4 seconds?
Velocity = Distance/Time = 28/1.4 = 20 m/s
A soccer player sprinting down the field demonstrates which form of energy?
kinetic
What is kinetic energy in soccer?
Anything from a person's legs kicking the ground to run, or kicking a ball.
A soccer player kicks a ball into the air and it lands far down the field Which energy conversion occurs as the ball falls from its highest point?
When a soccer player kicks a ball into the air, its kinetic energy is drained through air resistance and by the force of gravity. At its highest point, the ball has all of its vertical kinetic energy converted into potential energy. As the ball falls, this potential energy is converted back into kinetic energy. It should be noted that through the entire process of rising and falling the ball maintained horizontal kinetic energy being dissipated by resistance until it hit the ground and stopped.
Ball kicked into the air at an angle of 34.0 degrees above the horizontal the initial velocity of the ball is 25.0 ms How long is the soccer ball in the air?
the soccer ball in the air is at 56.o speed
