Forces and Motion

    Cards (80)

    • Speed equation

      speed = distance/time
    • m/s
      Meters per second
    • SLAP (Distance - Time graphs)

      Scale - Equal intervals per square
      Line - Straight or curved or sometimes join the dots
      Axes - Label with units
      Points - Plotted using a sharpe pencil
    • Mass equation
      Weight / gravitational field strength
    • What are the types of forces?

      - Contact
      - Spring
      - Applied
      - Air resistance
      - Normal
      - Tension
      - Friction
      - Non-contact
    • Balenced
      No movement
    • Unbalenced
      Forces are not equal and opposite, the objects will change speed, direction and shape
    • What 2 categories can all quantiles be split into?

      - Scalars
      - Vectors
    • Quantites
      Things we measure
    • Scalars
      Are just a quantity
    • Vectors
      Have quantity and direction
    • Examples of scalars

      - Distance m
      - Speed m/s
      - Power W
      - Energy J
      - Mass Kg
      - Density
    • Examples of vectors

      - Displacement M
      - Velocity m/s
      - Acceleration m/s squared
      - Force N
      - Weight N
      - Momentum
    • What objects feel a force of attraction?
      Objects with mass
    • Why so they feel forces of attraction?

      This is due to the gravitational force, also known as gravity
    • Why do we feel a force?

      Because the Earth has a mass as do we
    • What is this force that we feel?
      Weight
    • Weight
      The force on an object due to it's mass and gravitational field strength in that area
    • Mass
      Is how much particles/atoms an object has in it, measured in kg
    • Gravitational field strength
      Gravity varies depending on where we are in the universe
    • Newtons on Mercury
      4N
    • Newtons on Venus
      9N
    • Newtons on Earth
      10N
    • Newtons on Mars
      4N
    • Newtons on Jupiter
      26N
    • Newtons on Saturn
      11N
    • Newtons on Neptune
      12N
    • Newtons on Uranus
      12N
    • Weight equation

      Mass x gravitational field strength
    • What is force measured in?

      Newtons [N]
    • Why are they called newtons?
      After Sir Isaac Newton
    • What is the force of an apple landing on your head?
      About 1N
    • Contact forces
      Objects that need to be tounched
    • Non-contact forces

      Forces acting without being touched
    • What is weight?
      Gravitational pull on an object
    • Is weight contact?
      No
    • What is friction?

      2 objects rubbing against each other
    • Is friction contact?
      Yes
    • What is magnetism?
      2 Magnets
    • Is magnetism contact?
      No
