Motion of Particles
- Centripetal Force
- Force that keeps things turning in a circle
- Thsi increases when
the mass and velocity
are increased
- And decreases when
the radius of the circle
increases
- And decreases when
the radius of the circle
increases
- Force that keeps things turning in a circle
- Acceleration -Rate of change of velocity
- Centripetal acceleration
- Force = mass x acceleration
- Energy in crashes
- momentum=velocity x mass
- when one object hits the other and then stops
all of the momentum is passed onto the
second object
- If 2 balls have the same mass then the
second ball will move at the same velocity
as the first ball before the collision
- If 2 balls have the same mass then the
second ball will move at the same velocity
as the first ball before the collision
- If 2 moving objects of the same mass
collide and stick together the mass of
the 2 combined will be doubled so the
velcocity would be halfed
- Types of collision
- Elastic
- All kinetic
energy is
conserved and
passed on
- All kinetic
energy is
conserved and
passed on
- Inelastic
- Kinetic energy
is dispersed as
other types of
energy
- Kinetic energy

- Elastic
- work done = energy used
- momentum=velocity x mass
- Gravitational Potential Energy
- Work done = force x distance
- Measures in joules
- Measures in joules
- Work done = force x distance
- Kinetic Energy
- Matter and Antimatter
