Newton’s Laws of Motion

Newton’s Laws of Motion. First Law. If there is no resultant force (overall force) on an object, it does not accelerate it continues to move with constant speed in one fixed direction The speed could be zero – i.e. it stays still . Second Law.

  1. Newton’s Laws of Motion

  2. First Law • If there is no resultant force (overall force) on an object, it does not accelerate • it continues to move with constant speed • in one fixed direction • The speed could be zero – i.e. it stays still

  3. Second Law • If there is a resultant force (overall force) on an object, it does accelerate in the direction of the force • Acceleration proportional to force • More mass, smaller acceleration • Rate of Change in momentum = force OR • Force = change in momentum ÷ time

  4. Third Law • Forces come in pairs. If A exerts a force on B then B exerts a force on A • Forces are same size • In opposite direction • On different objects (A on B, B on A)

  5. Bradley Wiggins is a leading British cyclist. This question is about the forces on his bike. Complete the sentences. Choose the best words from this list. counter driving upthrust tension velocity work Bradley supplies the .................... force for the bike. Air resistance supplies the .................... force. For the speed to increase, the .................... force must be greater than the .................... force.
