FORCE AND MOTION
- Scalar
- Quantity having Magnitude but no direction
- Eg. DIstance, time, speed,etc.
- Vector
- Quantity having Magnitude and direction.
- Eg. Displacement, velocity, acceleration, force, etc.
- Velocity(m/s)=Ditimeplacement(m)/Time(s)
- v=d/t
- Acceleration(m/s^2)=Change in velocity(m/s)/Time(s)
- a=(v-u)/t
- Force
- Force(mg m/s^2)=Mass(mg) x Acceleration(m/s^2)
- F=ma
- Conservation of force
- Every action has an equal and opposite reaction
- that if the resultant force acting on a body is zero, it will
remain at rest or continue to move at the same velocity
- Weight
- Weight(mg m/s^2)=Mass(mg) x Gravitational Acceleration(m/s^2)
- W=mg
- Force
