Science Physics Paper 2
Define vector
Answer is : Magnitude and direction
Define scalar
Answer is : Magnitude only
What are 3 examples of vector quantities?
Answer is : E.g.
Velocity
Displacement
Acceleration
Force
Momentum
What are 3 scalar quantities?
Answer is : E.g.
Speed
Distance
Time
Mass
What does a displacement of 0 represent?
Answer is : Where the object started (e.g. the top of a cliff)
Why is a car going around a round about accelerating while at constant speed?
Answer is : Velocity is always changing due to the changing direction
Velocity changing = Acceleration changing
Car is always accelerating
Define force
Answer is : A push or pull that acts on an object due to the interaction with another object
What are the two types of forces?
, Answer is : Contact
Non-contact
Define contact force
Answer is : A force that acts when objects are physically touching
What are two examples of contact force?
Answer is : Normal contact force
Friction
How does normal contact force occur?
Answer is : Force is normal to the planes of contact (90 degrees)
How does friction occur?
Answer is : When surfaces and their roughness are moved in contact with another surface to
create friction
Define non-contact force
Answer is : A force that acts when objects are physically seperated
What are 2 examples of non-contact forces?
Answer is : Electrostatic
Gravitational attraction
How does electrostatic force occur?
Answer is : When a charge causes a force of attraction or repulsion
How does gravitational attraction occur?
Answer is : When mass creates a force of attraction due to gravity strength
How do you measure somethings weight?
Answer is : Force/newton metre
Calibrated spring balance
How does an objects gravitational field get stronger?
, Answer is : Larger mass
What does the gravitational field of all matter cause to all other matter?
Answer is : Attraction
How do scales measure mass?
Answer is : Scales measure weight
Divide by gravitational field strength
Give you your mass
What are the properties of the same person on two different planets?
Answer is : Same mass
Different weight
Why does the same person on two different planets have a different weight?
Answer is : Because the gravitational field strength would be different on both planets
How is acceleration in free fall created?
Answer is : Gravity
Define centre of mass
Answer is : The point weight the weight of an object is considered to act
Define resulting force
Answer is : A single force that represents the sum of all the forces acting on an object
How do you calculate the resultant force of two forces parallel?
Answer is : Add the forces in the same direction
How do you calculate the resultant force of two oppositely directional forces?
Answer is : Subtract the forces (force being subtracted is the negative direction)
What are the forces acting on a skydiver?
Answer is : Weight and air resistance
What are the stages of a skydiver's forces when falling?
