CORRECT ANSWERS PREPARATION SET
◉ What are the properties of vector quantities?
Answer: They have magnitude and an associated direction
◉ How can you represent a vector quantity using a symbol?
Answer: With an arrow where the length of the arrow represents the
magnitude, and the direction of the arrow the direction of the vector
quantity
◉ What is a force?
Answer: A push or pull that acts on an object due the interaction of
another object
◉ What is a contact force?
Answer: A force that acts between two objects that are physically
touching each other
◉ Name four contact forces
Answer: Friction, air resistance, tension and normal
,◉ What is Newton's Third Law of motion?
Answer: When a contact force acts between two objects, both
objects experience the same size force, but in opposite directions
◉ What is a non-contact force?
Answer: Non-contact forces are forces that act between two objects
that are not physically touching each other
◉ Name three non-contact forces
Answer: Gravitational force, electrostatic force and magnetic force
◉ What is weight?
Answer: The force acting on an object due to gravity
◉ What does the weight of an object depend on?
Answer: The gravitational field strength at the point where the
object is
◉ What is the equation that links weight, mass and gravitational
field strength?
Answer: Weight = mass x gravitational field strength if [W=mg]
,◉ What is the relationship between the mass of an object and its
gravitational field?
Answer: The more mass an object has the greater its gravitational
field
◉ What is the unit of gravitational field strength?
Answer: Newtons per kg [N/kg]
◉ What is the unit of weight?
Answer: Newtons (N)
◉ What is the unit of mass?
Answer: Kilograms (kg)
◉ What is the 'centre of mass' of an object?
Answer: A single point in an object where the weight may be
considered to act
◉ How do you measure weight?
Answer: Using a calibrated spring-balance (a newtonmeter)
◉ What's the relationship between the weight and the mass of an
object?
, Answer: They are directly proportional
◉ What is a resultant force?
Answer: A single force that replaces a number of forces acting on an
object that has the same effect as all of the original forces acting
together
◉ When does a force do work on an object?
Answer: When the force causes a displacement of the object
◉ What is the equation that links work done, force and distance?
Answer: work done = force × distance [W=Fs]
◉ What is the unit of work done?
Answer: Joules (J)
◉ When is one joule of work done?
Answer: When a force of one newton causes a displacement of one
metre; 1 joule = 1 newton-metre
◉ When work is done against the frictional forces acting on an
object what does it cause?
Answer: An increase in temperature of the object
