Firstly we write down all known variables: Initial speed (u)=0 m/s, Acceleration (a)=3 m/s2, Time (t)=5s. Final velocity (v)=?Therefore, the equation chosen to solve the problem would be: v=u+a...
The resultant force is firstly a key-word that any examiner will notice and so it will benefit your chance of getting the marks straight away. It helps us describe whether the forces are balanced or wheth...
c = EmΔt. With E being the thermal energy during the transfer, m being the mass of the substance, and Δt being the change in temperature.Usually they'll hide one of the values E, m or Δt in a different eq...
Explain the concept of momentum mathematically, then draw on physical intuition to reaffirm/deepen their understandingDiscuss how there exists a relationship between the rate of change of momentum and for...
An object will remain at rest or constant velocity if all the forces acting upon it are equal (net force=0N).
