material in a magnetic field. Electrostatic Force= Experienced by any
charged particles in a electric fieldGravitational Force= Experienced by any
mass in a gravitational field
◍ What is weight?.
Answer: The force acting on an object due to gravity.
◍ What causes gravity close to earth?.
Answer: The gravitational field around the Earth
◍ Weight Calculation?.
Answer: W= m x gW= weight, Newtons(N)m= Mass, Kilograms (kg) g=
gravitational field strength, Newtons per kilogram (N/kg)
◍ What is an object's "centre of mass"?.
, Answer: The point at which the weight of an object is considered to act
◍ 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)
◍ what is the relationship between the weight and mass of an object?.
Answer: the weight is directly proportional to the mass of an objectweight
mass
◍ How can we measure weight?.
Answer: Using a spring balance (newtonmeter)
◍ What is a resultant force?.
Answer: The single force that replaces multiple forces acting at a single
point
◍ If forces acting on an object combine to give a resultant force of zero:.
Answer: the object is in equilibrium.
◍ What is Work Done?.
Answer: energy transferred(When a force causes an object to move through
a distance (when the object is displaced))
◍ If a object is elastically deformed.
Answer: it can go back to it's original shape and length after the force has
been removed.
◍ How do you calculate Work done?.
Answer: W= f x dW= work done measured in Newton Metres Nmf= Force
measured in Newtons d= distance measured in metres m
, ◍ 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
◍ eg) what happens when work is done against the frictional forces acting on
an object?.
Answer: There is a rise in temperature of the object
◍ What is the spring constant?.
Answer: How stiff the spring is, the stiffness depends on the material used.
◍ what is it called when an object changes shape?.
Answer: Deformation
◍ What are the three types?.
Answer: stretching, bending or compressing
◍ On a spring constant graph, what does a curve show?.
Answer: It shows the extension is no longer proportional to force.
◍ How can the shape of an object be changed.
Answer: By applying more than one force
◍ What is elastic deformation?.
Answer: If the object returns back to its original shape once the forces are
removed
◍ 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
◍ what is inelastic deformation?.
Answer: If the object do not return back to its original shape once the forces
