GRADE 7

• Is a change in the position of an object with respect to a reference of point

  motion
• branch of physics that deals with descriptive study of motion

  Kinematics
• are in straight path, or rectilinear

  motion
• what are the 5 quantities that describes motion?


  Distance, displacement, speed, velocity, and acceleration
• Described by its magnitude and appropriate unit

  scalar
• no direction is required

  scalar
• the one that requires direction

  vector
• example of scalar

  distance, speed, mass, power, energy, and work
• example of vector

  displacement, velocity, acceleration, force, and momentum
• Is a scalar quantity

  Distance
• Is a vector quantity

  Displacement
• Refers to the actual length of path traveled by an object from its initial point to its final position

  distance
• Refers to the straight-line distance between the initial and final position

  displacement
• quantity used to describe the distance traveled per unit time

  speed
• its common units are km/h or kph

  speed
• Also, it describe the rate of change of position

  speed
• speed is a scalar quantity

  true
• How fast or slow the travel it is

  Velocity
• It is considers the displacement per unit time

  velocity
• velocity is a vector quantity

  true
• velocity is a scalar quantity

  false
