This is the formula for calculating speed
Speed = Distance ÷ Time
This is the unit of force
Newton (N)
This is the unit of energy
Joule (J)
This is the unit of frequency
Hertz (Hz)
This is the part of the electromagnetic spectrum that humans can see
Visible Light
This is the term for the speed of an object in a given direction
This is the force that pulls objects toward the centre of the Earth
Gravity
This is the type of energy stored in food or fuel
Chemical Energy
This is the type of wave where particles vibrate parallel to the direction of energy transfer
Longitudinal Wave
This is the type of electromagnetic wave used in satellite communications
Radio Waves
This is the acceleration of an object that increases its velocity from 10 m/s to 30 m/s in 5 seconds
4 m/s²
This is the resultant force when two forces of 10 N and 15 N act in opposite directions
5N
This is the energy transferred when a 2 kg object is lifted 5 meters vertically
100J (Use PE = mgh, g = 10 m/s²)
This is the wavelength of a wave with a frequency of 50 Hz and a speed of 100 m/s
2 metres
This is the speed of light in a vacuum
3.00 x 108 m/s
This is the term for the straight-line distance between an object’s starting and ending points
Displacement
This is Newton’s Third Law of Motion
For every action, there is an equal and opposite reaction
This is the principle that states energy cannot be created or destroyed
The Law of Conservation of Energy
This is the term for the maximum displacement of a wave from its rest position
Amplitude
This is the process by which light bends when it passes from one medium to another
Refraction
This is the shape of a distance-time graph for an object moving at constant speed
Straight Line
This is the force needed to accelerate a 5 kg object at 3 m/s²
15N
This is the efficiency of a device that outputs 80 J of useful energy from 200 J of input energy
40%
This is the speed of a wave with a wavelength of 10 meters and a frequency of 20 Hz
200 m/s
This is the order of the electromagnetic spectrum from longest to shortest wavelength
