P2.1 Motion

• Displacement is the total length of the path traveled by an object.

  False
• There are three main types of motion: linear, circular, and rotational.
• Match the type of motion with its example:

  Linear motion ↔️ Car driving on a straight road

  Circular motion ↔️ Planet orbiting the sun

  Rotational motion ↔️ Wheel rotating on its axle
• Give an example of an object undergoing linear motion.

  Car driving on a road
• Velocity is the rate at which an object covers distance.

  False
• Circular motion is motion in a circular path around a fixed point.
• The total length of the path traveled by an object is called distance.
• What is the unit of measurement for velocity?

  meters per second
• Closer spacing in a motion diagram indicates faster velocity.

  False
• What does wider spacing between positions in a motion diagram indicate?

  Faster velocity
• Motion diagrams are visual representations that depict the motion of an object over time
• What does wider spacing between positions in a motion diagram indicate?

  Faster velocity
• Arrange the following types of motion based on their defining characteristics:

  1️⃣ Linear motion: Motion in a straight line

  2️⃣ Circular motion: Motion in a circular path

  3️⃣ Rotational motion: Motion around a fixed axis
• The key quantities used to describe motion are displacement, velocity, and acceleration.
• A car driving down a straight road exhibits linear motion.


  True
• Distance is a scalar quantity, while displacement is a vector quantity.
• In a motion diagram, how is velocity represented?

  Spacing between positions
• Match the graph type with what it represents:

  Distance-time graph ↔️ Displacement over time

  Speed-time graph ↔️ Velocity over time
• Motion can be represented graphically using two main types of graphs: distance-time and speed-time graphs
• What does the slope of a distance-time graph represent?

  Speed
• A curved line on a distance-time graph indicates changing speed.

  True
• What does the slope of a speed-time graph represent?

  Acceleration
• An increasing line on a speed-time graph indicates acceleration.


  True
• A car accelerating from rest would have a curved, increasing distance-time graph.


  True
• Order the steps involved in analyzing motion using graphs:

  1️⃣ Interpret the slope

  2️⃣ Analyze the area under the curve

  3️⃣ Understand the type of graph
• The slope of a speed-time graph represents the object's acceleration
• What is the formula for average speed?

  Total distance / Total time
• Average speed is a scalar quantity, while average velocity is a vector quantity.


  True
• Match the motion quantity with its definition:

  Displacement ↔️ Change in object's position

  Velocity ↔️ Rate of change of position

  Acceleration ↔️ Rate of change of velocity
• Velocity is the rate of change of an object's position
• Match the type of motion with its example:

  Linear Motion ↔️ Car driving straight

  Circular Motion ↔️ Planet orbiting the sun

  Rotational Motion ↔️ Spinning wheel
• What is circular motion defined as?

  Movement in a circular path
• A car driving straight on a highway exhibits linear motion.
• What is the definition of distance?

  Total length of path traveled
• What is the definition of speed?

  Rate of covering distance
• Distance is a scalar quantity, while displacement is a vector quantity.


  True
• The formula for average speed is total distance divided by total time.
• If an object travels 100 meters east and then 100 meters west in 20 seconds, its average velocity is 0 m/s.


  True
• In a motion diagram, closer spacing between positions indicates slower velocity.
• Match the graph type with what it represents:

  Distance-Time Graph ↔️ Displacement over time

  Speed-Time Graph ↔️ Velocity over time
