Motion and Force. Motion An object is in motion if the object changes position relative to a reference point Essentially, everything is in motion.

Vector, or Scalar?. Some physical quantities have a direction, and some do not.

Wave Properties. Amplitude The distance a wave vibrates from its rest position. The distance a wave vibrates from its rest position. The greater the amplitude,

Work = work is done when a net force on an object causes it to move a distance W = Fd Or Work (measured in joules) = Force (N) times Distance (m) Is work.

PROPERTIES OF WAVES. Waves A wave is a means of transferring energy and information from one point to another without there being any transfer of matter.

What’s the Unit?. Most physical quantities have units. You need to know the SI unit for each quantity you use.

Units quiz Give the units for the following: Energy Force Power Work Frequency Time Resistance

Answers Give the units for the following: Energy Joules J Force Newtons N Power Watts W Work Joules J Frequency Hertz Hz Time Seconds S Resistance Ohms Ω

Now try these Acceleration Specific latent heat Specific heat capacity Momentum Density Velocity (speed)

Answers Acceleration m/s2 Specific latent heat J/kg Specific heat capacity J/kg/oC Momentum Ns Density kg/m3 Velocity (speed) m/s

Give the word equations to find the following Weight Wave speed Potential difference Energy transferred Density Magnification Distance travelled

Answers Weight = mass x gravitational field strength Wave speed = frequency x wavelength Potential difference = current x resistance Energy transferred = power x time Density = mass/volume Magnification = image height/object height Distance travelled = speed x time
