Force

• A force is a push or pull that acts on an object

  $Force=$$mv^2/r$
• f=force

  m=mass

  v=velocity

  r=radius
• Forces are vector quantities therefore have magnitude(size)and direction.
• Mass is the amount of matter in an object

  Weight is the force of gravity on an object
• $Weight(in Newtons)=$$mass(in kg)x gravitational field strength (in N/kg)$
• Weight(in Newtons)= mass(in kg)x gravitational field strength(in N/kg)

  Force=mass x area

  • Gravitational field strength =10N/kg
• Scalars and Vectors

  A Scalar quantity has magnitude(size) only

  A Vector quantity has magnitude and direction
• TANcent= opposite/adjacent
• If it is COSine=adjacent/hypotenuse.
• If it is SINe=opposite/hypotenuse
