Newton's first law
If no force is acted upon an object then its velocity remains constant.
1 of 9
Newton's second law
F=MA - A is directly proportional to force and is inversely proportional to M
2 of 9
Newton's third law
Every action has an opposite and equal reaction
3 of 9
Define Impulse
The change in momentum due to force
4 of 9
Equation for momentum
mv
5 of 9
In circular motion, is kinetic energy constant?
Yes
6 of 9
Define free oscillation
Oscillation in air, same amplitude and no energy loss. This never happens
7 of 9
Define forced vibration
When a system is forced to vibrate by a periodic external force, the frequency of this is called the driving frequency.
8 of 9
How is the damping force acting on a vibrating system related to the velocity?
It is in the opposite direction.
