Electromagnetic Force - ANSWER A fundamental force that causes interactions
between charged particules. Virtual photons are the exchange particles
Gravitational Force - AN...
What happens to voltage and current in a parallel circuit? - ANSWER ✔ Voltage
is the same / current splits at junctions
What happens to voltage and current in a series circuit? - ANSWER ✔ Voltage
splits across components / current is the same
EMF (electromotive force) - ANSWER ✔ The total energy supplied per coulomb
of charge by the cell
Convectional current - ANSWER ✔ Positive to negative
Electron flow in a circuit - ANSWER ✔ Negative to positive
Potentiometer - ANSWER ✔ Variable resistor
Wave - ANSWER ✔ An oscillation which transfers energy from a source to a
destination without transferring matter
,Transverse wave - ANSWER ✔ The oscillations are perpendicular to the direction
of energy transfer
Longitudinal wave - ANSWER ✔ -The oscillations are parallel to the direction of
energy transfer
-The particles rarefact and compress
Amplitude - ANSWER ✔ The displacement from the rest position to the peak or
trough
Wavelength - ANSWER ✔ Distance from a point on one wave to the identical
point in the successive wave
Frequency - ANSWER ✔ The number of whole oscillations per second
Instantaneous velocity - ANSWER ✔ The velocity of an object at an instant / at a
specific point in the object's path
Velocity - ANSWER ✔ Speed in a given direction
Fluid - ANSWER ✔ A substance that flows (liquid or gas)
Impulse - ANSWER ✔ Change in momentum
Period - ANSWER ✔ The time taken for a whole cycle to complete or pass a
given point
What word do we use to describe the situation when all forces acting on an object
are balanced? - ANSWER ✔ Equilibrium
What do forces acting on an object in equilibrium produce? - ANSWER ✔ Closed
loop
What does the principle of moments state? - ANSWER ✔ For a body in
equilibrium the sum of the clockwise moments is equal to the sum of the
anticlockwise moments.
, What is a couple (moments)? - ANSWER ✔ A pair of forces equal in size that are
parallel to eachother, but in opposite directions.
What is meant by the centre of mass? - ANSWER ✔ A single point on an object
that you can consider the whole weight of the object to act through.
When do we use SUVAT equations? - ANSWER ✔ When acceleration is
unifrom.
What is the gradient of a displacement-time graph equal to? - ANSWER ✔
Velocity
How do we determine acceleration from a displacement-time graph? - ANSWER
✔ The rate of change of the gradient.
How do we find instantaneous velocity from a displacement-time graph? -
ANSWER ✔ Use a tangent
How do we determine acceleration from a velocity-time graph? - ANSWER ✔
Gradient
How do we find the displacement from a velocity-time graph? - ANSWER ✔
Area beneath the curve
How do we find velocity from an acceleration-time graph? - ANSWER ✔ Area
beneath the curve
What does a positive value on an acceleration-time graph represent? - ANSWER
✔ Object accelerating
What does a negative value on an acceleration-time graph represent? - ANSWER
✔ Object decelerating
What is Newton's first law? - ANSWER ✔ The velocity of an object remains
constant unless a resultant force acts on it.
