  • unit for force is?
    neutons
  • scaler quantities only have ?
    magnitude eg distance and speed
  • what is a force
    can be a pull or push on an object caused by an intraction with another object
  • forces are a ......
    vector quantities
  • what are contact forces ?
    occur when 2 objects are touching each other
    example ....
    friction
    airresistence
    tension
    normal cpntact force
  • non-contact forces are?
    act at a distance withought two objects touching
    for example:
    garvitational force
    electrostatic force
    magnetic force
  • when an object exerts a force on another object, it will experience an equal and opposite force
  • what is the equation for spring constant
    force applied(n)=spring constant(n/m)x extention (m)
  • what is a scaler quantity ?
    only has a size (magnitude)
  • what is a vector quantity?
    has both size and direction
  • is a force vector or scaler quantity?
    vector
  • what is a contact force?
    when objects are physically touching
  • what is the same about the intraction pair of forces when 2 forces intract with eachother?
    the forces are the same size
  • what is the name for the force on an object that has balaced forces ?
    zero
  • what is elastic deformation?
    an object can go back to its original shape and size when deformation force is removed
  • what is inelastic deformation ?
    an object that does not go to its original shape and size after the deformation force is removed
