SOLUTIONS GRADED A+
◉ Force is a. Answer: vector quantity
◉ What do vectors have. Answer: Direction and magnitude. Force,
velocity, displacement, acceleration, momentum
◉ What do scalar have. Answer: Direction. Speed, distance, mass,
temperature, time
◉ A force can be a. Answer: push or a pull
◉ When two objects have to be touching for a force to act,. Answer:
that force is called a contact force.
◉ If the objects do not need to be touching for the force to act,.
Answer: the force is a non-contact force.
◉ Name some contact forces. Answer: Friction, air resistance
,◉ Name some non-contact forces. Answer: Magnetic, gravitational,
electrostatic
◉ What is weight?. Answer: The force acting on an object due to
gravity.
◉ Weight =. Answer: Mass (Kg) x Gravitational Field Strength (N/kg)
◉ What is the resultant force?. Answer: It is the forces combined to
show the result of the overall force.
◉ When a force moves an object through a distance,. Answer: energy
is transferred and work is done.
◉ Work Done (J) =. Answer: Force (N)x Distance (m)
◉ If forces acting on an object combine to give a resultant force of
zero:. Answer: the object is in equilibrium.
◉ If a object is elastically deformed. Answer: it can go back to it's
original shape and length after the force has been removed.
, ◉ An object has been inelastically deformed. Answer: if it doesn't
return to it's original shape and length after the force has been
removed.
◉ (For springs) Force (N) =. Answer: Spring constant x Extension
◉ What is the spring constant?. Answer: How stiff the spring is, the
stiffness depends on the material used.
◉ On a spring constant graph, what does a curve show?. Answer: It
shows the extension is no longer proportional to force.
◉ The point where the extension is no longer proportional to the
force is the. Answer: limit of proportionality
◉ Work done in stretching a spring can be found using this
equation:. Answer: E = 1/2 x ke^2 or Elastic potential energy - 1/2
spring constant / extenstion^2
◉ Speed is. Answer: how fast you're going with no regard to the
direction.
◉ Velocity is. Answer: a speed in a given direction
