Motion Particles

Question 1

What is the lhc and what does it do and for

Answer 1

A particle accelerator. It accelerates two beams of protons or ions and collides them head on from opposite directions in the hope of discovering new particles

Question 2

What keeps a hammer through going in a circle

Answer 2

A inward acting resultant force, the centripetal force

Question 3

How does a cyclotron make particles go in a circular motion

Answer 3

A constant magnetic field is applied at right angles to the particle which creates the centripetal force needed

Question 4

How does a cyclotron work

Answer 4

A voltage is placed between two d shaped magnetic field regions, this is what accelerates the particles. As they speed up, there path spirals outwards towards an exit when it then exits at a tangent towards its target

Question 5

Momentum formula

Answer 5

Mass * velocity

Question 6

Collision rules for elastic and inelastic collisions

Answer 6

Elastic, all momentum conserved, all kinetic energy conserved
Inelastic, all momentum conserved, some kinetic energy transferred into other forms of energy such as heat

Question 7

What is antimatter

Answer 7

Matter with the same mass of normal matter but opposite charge, positron is antimatter of electron

Question 8

What happens when an electron and positron collide

Answer 8

Annihilation occurs, the mass of the two particles becomes gamma rays

Question 9

What is formula for energy that can be produced by something of mass

Answer 9

E = m*c^2
E is energy in joules
M is mass in grams
C is lightspeed

Question 10

What is lightspeed

Answer 10

3x10^8 m/s
