Motion with constant acceleration
As it was the case with velocity, if the motion takes place with constant acceleration, then, at any
point, the instantaneous and average accelerations are equal, or a a . If we assume that the
initial time t0 = 0 (we sta
Static Equilibrium
Equilibrium of a particle and a rigid body:
According to Newtons second law a particle is
at equilibrium if:
Fnet 0
This gives:
Fnetx 0
FnetY 0
This condition is enough because the particle has a very small radius that tends to zero as
Rotation
a) Point particle in circular motion:
Consider a particle of mass m rotating around a point O on a circular path with
radius r.
The particle linear velocity along the tangential
v
axis is given by:

Newtons Laws
Summary:
So far, we have studied motion in 1 and 2 dimensions without taking into account
what made the objects move. We know, however, that if an object is at rest, for it to start
moving we need to do something, such as pushing it. That som
Kinetic energy, Work and Power
Work done by constant force
Work, is the energy transferred to (or from) an object due to the action of force.
The work W done by a constant force of magnitude F and direction , measured with
respect to the direction of moti

Inelastic Collision
Inelastic collision:
Practically; most of collisions are not perfectly elastic. The linear
momentum of the system before and after collision is conserved but the kinetic energy is
not. Some of the initial kinetic energy g
