- Forces Revision
- Vector Quantites
- Force
- Measured in Newtons (N)
- Velocity
- Displacement
- Acceleration
- Equation: Change of velocity/Time taken.
- Unit of measurement:m/s^2
- Momentum
- Momentum = Mass x Velocity
- Vectors are represented by arrows and the length being the magnitude and the direction shows the direction of the object
- Force
- Scalar Quantites
- Speed
- Distance
- Mass
- Mass is measured in kilograms
- Temperature
- Time
- Time is measured in seconds.
- Contact Force
- Friction
- Air Resistance
- Tension in ropes
- Normal contact force
- Non-Contact Force
- Magnetic Force
- Gravitational Force
- The gravitational force here on Earth is 9.8N/kg
- Electrostatic Force
- Newton's Laws
- Newton's First Law
- If there is no force, there is no change in velocity
- Newton's Second Law
- The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object
- Newton's Third Law
- For every action, there is an equal and opposite reaction
- Newton's First Law
- Equations
- Weight(N)=Mass(kg) x Gravitational Field Strength
- Distance(m) = Speed(m/s) x Time(s)
- Momentum = Mass x Velocity
- Work done(J) = Force(N) x Distance(m)
- Force = Spring Constant (N/m) x Extension(m)
- Resultant Force = Mass x Acceleration.
- Good old facts?
- Weight and Mass are directly proportional!
- The centre of mass is the place you think most of the mass is concentrated in.

- Forces and Elasticity
- Elastic Deformation
- An object has been elastically deformed if it can return into shape.
- Inelastic Deformation
- An object has been inelastically deformed if it cannot return back into shape
