STUDY GUIDE
◉ Name the vector quantities.
Answer: acceleration, displacement, velocity, magnetic flux density,
momentum, force, impulse
◉ Name the scalar quantities.
Answer: distance, speed, energy, volume, area, electric field strength
◉ What is Newton's first law?.
Answer: the velocity of an object won't change unless a resultant
force acts on it. This means a body will stay still or move in a straight
line at a constant speed unless there's a resultant force acting on it
◉ What is Newton's second law?.
Answer: resultant force = mass x acceleration, this means a larger
force acting on an object causes a larger acceleration, and a larger
mass means a smaller acceleration for a given force
, ◉ What is Newton's third law?.
Answer: if an object A exerts a force on object B, the object B exerts
an equal but opposite force on object A. This means every action has
an equal and opposite reaction
◉ How to add vectors?.
Answer: use the scale given. Draw the vectors to correct lengths and
angles. Follow arrows from tip to tail. The final displacement from
the starting point is called the resultant vector
◉ Define component vector.
Answer: vectors that can replace a vector as they have the same
effect, when combined
◉ What does the gradient represent in a displacement time graph?.
Answer: velocity
◉ What does a straight line represent in a displacement time graph?.
Answer: constant velocity
◉ What does a curve represent in a displacement time graph?.
Answer: changing velocity and object is accelerating
