Physical World
- Fundamental Forces in Nature
- Gravitational Force
- Force of mutual attraction
between any two objects by
virtue of their masses
- Universal Force
- Every object experiences this force
- Force of mutual attraction
between any two objects by
virtue of their masses
- Electromagnetic Force
- Force between charged particles
- When charges are at rest,
EM force is given by
Coulomb's Law
- Acts over large distances
- Doesn't need intervening
medium
- Force between charged particles
- Strong Nuclear Force
- Strongest fundamental force
(EM*100)
- Charge Independent
- Very small range
(10^-15 m)
- Electron does not
experience this force
- Strongest fundamental force
(EM*100)
- Weak Nuclear Force
- Appears in
beta-decay
of nucleus
- Nucleus emits an electron and an
uncharged particle called neutrino
- Nucleus emits an electron and an
uncharged particle called neutrino
- Very small range
(10^-16 m)
- Appears in
beta-decay
of nucleus
- Gravitational Force
- Physical Laws
- Law of Conservation of Energy
- The sum of kinetic and potential
energy of a body is constant
- The sum of kinetic and potential
energy of a body is constant
- Law of Conservation of Mass
- Mass can neither be created nor destroyed
- Mass can neither be created nor destroyed
- Law of Conservation of Momentum
- Total linear momentum and
total angular momentum of
isolated system are conserved
- Total linear momentum and
total angular momentum of
isolated system are conserved
- Law of Conservation of Energy
