Warming up the body

Activity 1:

To warm up the body before activity can be executed

[lo 1.1]

  • Before you can attempt any of the activities you must warm up your body. The warm-up reduces the risk of injury and will make the dances easier to do. It will be easier and more fun if you do the warm-up with music. Choose music that is not too fast.

Preparation - stand with feet hip-width apart, feet facing forward, arms down. Remember:

  • It is important to keep your body alignment in order to isolate the specific muscles that are being warmed up.
  • Correct body alignment will prevent injuries.
  • Only move the body parts and muscles prescribed.

Breathing exercise

  • Inhale through your nose for four counts and raise your arms gradually sideways.
  • Stretch your spine.
  • Exhale through your mouth for four counts, and gradually lower your arms.
  • Repeat the breathing exercise.
  • Stand with your feet a hip-width apart, knees bent slightly, arms at your sides.

Side Stretching

  • Lift right arm slowly sideways to straight above the head.
  • Bend upper body to the left.
  • Circle right arm down as left arm circles up.
  • Repeat with left arm and bend to the right.
  • Bend again to the left.
  • Circle left arm – stretch right into a V position.
  • Lower both arms to an A position.
  • Repeat four times.
  • keep the movements strong and smooth in time to the music;
  • execute full range of motion;
  • keep your head in line with your spine at all times.

Walking

  • Walk eight steps forward – letting arms swing freely.
  • Close feet – relax whole body.
  • Bend upper body forward – knees bent and hold for a beat.
  • Stretch up arching spine – arms up in an A.
  • Hold for a beat.
  • Repeat bending and arching of spine section.
  • Walk backwards for eight counts.
  • Repeat bending an arching of spine section twice.
  • Repeat whole exercise four times.
  • the stretching up should not be strained; just leading up to a fuller relaxation on the forward position;
  • the whole movement should be continuous;
  • do not relax your neck and head;
  • do not lock your knees.

Walking with Arm-warm-up

  • Walk forward for four beats.
  • Walk backward for four beats.
  • Walk to the right for four beats.
  • Turn around and walk to the left for four beats.
  • Repeat four times.
  • Repeat walking exercise and raise arms to shoulder height forward.
  • Make fists and push arms forward and back on every beat when walking forward.
  • Walk backward and push arms above your head and back on every beat.
  • Repeat eight times.

Combination

  • Repeat the first walking exercise and add the second walking exercise in a combination.
  • Repeat eight times.
  • You are welcome to change the arm movements.

Quadriceps warm-up

  • Walk forward – leading with your right leg - for three counts – lift your left leg forward and up on the fourth beat.
  • Walk to the right for three counts – lift your leg on the fourth beat.
  • Turn to the back – walk to the back (not backwards) – for three counts – lift your leg on the fourth beat.
  • Turn to the right and walk for three counts – lift your leg on the fourth beat.
  • Turn to face the front (you should have made a ‘square’ formation).
  • Lift your legs – alternating right and left for eight counts.
  • Start the exercise again, this time leading with the left leg.
  • After the square have been completed, lift your legs alternating left and right for eight counts.
  • Repeat the whole exercise four times.

Questions & Answers

Three charges q_{1}=+3\mu C, q_{2}=+6\mu C and q_{3}=+8\mu C are located at (2,0)m (0,0)m and (0,3) coordinates respectively. Find the magnitude and direction acted upon q_{2} by the two other charges.Draw the correct graphical illustration of the problem above showing the direction of all forces.
Kate Reply
To solve this problem, we need to first find the net force acting on charge q_{2}. The magnitude of the force exerted by q_{1} on q_{2} is given by F=\frac{kq_{1}q_{2}}{r^{2}} where k is the Coulomb constant, q_{1} and q_{2} are the charges of the particles, and r is the distance between them.

What is the direction and net electric force on q_{1}= 5µC located at (0,4)r due to charges q_{2}=7mu located at (0,0)m and q_{3}=3\mu C located at (4,0)m?

what is a capacitor?
Raymond Reply
Capacitor is a separation of opposite charges using an insulator of very small dimension between them. Capacitor is used for allowing an AC (alternating current) to pass while a DC (direct current) is blocked.

velocity can be 72 km/h in question. 72 km/h=20 m/s, v^2=2.a.x , 20^2=2.a.50, a=4 m/s^2.

which has a higher temperature, 1cup of boiling water or 1teapot of boiling water which can transfer more heat 1cup of boiling water or 1 teapot of boiling water explain your . answer
Ramon Reply
I believe temperature being an intensive property does not change for any amount of boiling water whereas heat being an extensive property changes with amount/size of the system.
Someone
Scratch that
Someone
temperature for any amount of water to boil at ntp is 100⁰C (it is a state function and and intensive property) and it depends both will give same amount of heat because the surface available for heat transfer is greater in case of the kettle as well as the heat stored in it but if you talk.....
Someone
about the amount of heat stored in the system then in that case since the mass of water in the kettle is greater so more energy is required to raise the temperature b/c more molecules of water are present in the kettle
Someone
definitely of physics

how do lnternal energy measures
Esrael
Two bodies attract each other electrically. Do they both have to be charged? Answer the same question if the bodies repel one another.
JALLAH Reply
No. According to Isac Newtons law. this two bodies maybe you and the wall beside you. Attracting depends on the mass och each body and distance between them.
Dlovan
Are you really asking if two bodies have to be charged to be influenced by Coulombs Law?

What is specific heat capacity
Destiny Reply
Specific heat capacity is a measure of the amount of energy required to raise the temperature of a substance by one degree Celsius (or Kelvin). It is measured in Joules per kilogram per degree Celsius (J/kg°C).
