Waves: longitudinal, transverse, amplitude and speed
Fichas del conjunto (18)
- 1What is a Longitudinal Wave?They have oscillation at right angle from the energy
Light and other types of electromagnetic radiation - 2What is a Transverse Wave?Light and other types of electromagnetic radiation are transverse waves. Water waves and S waves (a type of seismic wave) are also transverse waves. In transverse waves, the vibrations are at right angles to the direction of travel.
- 3What is amplitude?The amplitude of a wave is its maximum disturbance from its undisturbed position.
- 4What is the Wavelength?The wavelength of a wave is the distance between a point on one wave and the same point on the next wave.
- 5What is the Frequency?The frequency of a wave is the number of waves produced by a source each second. The unit of frequency is in hertz (Hz).
- 6What are waves?Waves are vibrations that transfer energy from place to place without matter - solid, liquid or gas - being transferred.
- 7What is the equation to work out the average speed?
- 8What is average speed measured in?measured in metres per second, m/s
- 9What is distance moved measured in?measured in metres, m
- 10What is the equation for acceleration?
- 11What is Velocity?The velocity of an object is its speed in a particular direction.
- 12What could affect a drivers Thinking Distance?tired, under the influence of alcohol or other drugs, distractions - phones, music, people, other vehicles
- 13What is the gradient?The slope on a graph. The gradient of a distance - time graph represents speed.
- 14What is the Stopping Distance?The total distance needed to stop a car. Made up of the Breaking Distance and the Thinking Distance.
- 15What is Terminal Velocity?Where there is no resultant force and the object reaches a steady speed.
- 16Terminal Velocity
- 17What is air resistance?his is a frictional force acting in the opposite direction to the movement of the object.
- 18What is the Breaking Distance and what affects it?The distance taken to stop once the brakes are applied. - The car's brakes or tyres are in a poor condition -There are poor road and weather conditions -The car has a larger mass
