Every year people makes these mistakes in exams. Don't let it be you
Forgetting that the signs of x, a, v and u in the equations of motion can be postive or negativeConfusing the meaning of the area under a graph with the gradient of the line or curve.
Using v= d/t to work out the velocity at a point in time when the object is accelerating
Using the equations of motion to investigate the horizontal motion of a projectile
Forgetting that if an object is travlling with constant velocity the resultant force is 0
Forgetting that using Newton's third law the two forces act on different objects
Forgetting that equilibrium means the forces are balanced
Confusing the distance used to calculate work done with the distance used to calculate moments
Forgetting to use the perpendicular distance from the force to the pivot when calculating moments
Saying that momentum is lost in an inelastic collision
Forgetting that it is kinetic energy that is converted into other forms of energy in an inelastic collision
Not realising that Alpha particles are the most ionising form of radiation
Thinking that Beta (β) particles come from electron shells of the atom
