AQA Physics Higher Combined - Paper 2
How can a vector quantity be represented? - ANS-By an arrow in the direction of the vector and
of length in proportion to the magnitude of the vector.
If two forces act on an object in opposite directions and the resultant force isn't zero, what will
the resultant force be? - ANS-The difference between the forces and in the direction of the
larger force.
If two forces act on an object in the same direction and the resultant force isn't zero, what will
the resultant force be? - ANS-The sum of the forces in the same direction of both forces.
What are contact forces? - ANS-If two objects much touch each other to interact, the forces are
contact forces.
What are examples of contact forces? - ANS-• friction
• air resistance
• tension in ropes
What are examples of non-contact forces? - ANS-• magnetic force
• gravitational force
• electrostatic force
What are examples of scalar quantities? - ANS-• distance
• speed
• time
• mass
• energy
• power
What are examples of vector quantities? - ANS-• displacement
• velocity
• force
• weight
• momentum
• acceleration
What are forces measured in? - ANS-Newtons (N).
What are scalar quantities? - ANS-Scalar quantities have magnitude (size) but no direction.
What are three different things forces can do on objects? - ANS-• change shape of object
