Science

• Distance - It is the total path length taken by an object from one point to another
• Displacement - It is defined as the shortest length between two points.
• Speed - It tells how fast an object is moving with respect to time.
• Velocity - It tells how fast an object is moving in a certain direction with respect to time.
• Distance - It is the total path length taken by an object from one point to another
• Displacement - It is defined as the shortest length between two points.
• to solve for distance, you need to add up the total path taken and the total distance travelled
• to solve for displacement, sum the initial position and the finale position
• to solve for the speed, you must divide the distance and time
• to solve for velocity, you need to divide distance and time
• Scalar Quantities - Distance Speed Mass Temperature
• Vector Quantities - Displacement Velocity Force Acceleration
• Distance are defined with length (Kilometer, Meter, Miles, Centimeter)
• A waves carries energy from one point to another.
• Mechanical waves require a medium for them to travel.
• Transverse waves is a wave in which a medium vibrates in a direction Perpendicular to the direction of the traveling particle.
• The distance between identical parts of the wave is called wavelength
• The Amplitude refers to the distance from midpoint to the crest or from midpoint to the trough of the wave
• Wave Propagation is the movement of waves through a medium or vacuum.
• Electromagnetic Waves dont require a medium
• Mechanical Waves needs a medium or a matter
• Transverse Waves is a waves up and down direction
• Longitudinal Waves is a waves that form vibration moves parallel to the direction of the travel.
• Crest - Highest point of the wave
• Wavelength - The distance between identical parts of the wave
• Equilibrium - The origin position of a medium
• AMPLITUDE - refers to the distance from midpoint to the crest or from midpoint to the trough of the wave
• Trhough - Lowest point of the wave
• Frequency (f) - shows how frequent a vibration takes place.
• Amplitude – maximum displacement of a point of a wave from its rest position
• Sound wave is the vibration that travel through any medium and can be heard
• A Sound is classified as a mechanical and a longitudinal wave
• How Do Human and Other Organisms Produce Sound? This is because of your vocal cords in the larynx (voice box).
• Men have a vocal cord length of 20 mm, whereas women have a shorter vocal cord of 15 mm. Children have the shortest vocal cords in comparison to adults.
• Animals produce sound as well. They use sound for communicating, for attracting mates, and for defending themselves.
• Loudness is how loud or soft the sound relative to a listener
• Intensity is the measure of the amount of energy used to produce the vibration in the medium.
• Pitch refers to the highness and lowness of sound.
• LIGHT - Is a form of energy found in our surroundings.
• Light travels in a straight line
