CIE IGCSE Physics
Speed= - correct answer ✔distance÷time


What is the shape of a distance-time graph when the object is at rest? -
correct answer ✔a horizontal line


What is the shape of a distance-time graph when the object is moving with
constant speed? - correct answer ✔a slanted line


What is the shape of a distance-time graph when the object is moving with
changing speed? - correct answer ✔a curved line


What is the distance traveled for motion with constant acceleration in a speed-
time graph? - correct answer ✔the area under the graph


If a body accelerates its speed-time graph will have a... - correct answer
✔positive gradient


If a body decelerates its speed-time graph will have a... - correct answer
✔negative gradient


What is the difference between speed and velocity? - correct answer
✔Velocity is a vector while speed is scalar. Velocity has a direction.


a = - correct answer ✔∆v÷t


Speed (on a distance-time graph) = - correct answer ✔the gradient

,Acceleration (on a speed-time graph) = - correct answer ✔the gradient


On a speed-time graph, a straight line with a positive gradient means... -
correct answer ✔constant acceleration


On a speed-time graph, a curved line with a positive gradient means... -
correct answer ✔changing acceleration


Deceleration= - correct answer ✔negative acceleration


The mass of a body = - correct answer ✔the number of particles it has


Weight is a _____________ force - correct answer ✔gravitational


What is the difference between mass and weight? - correct answer ✔Weight
is affected by gravitational field strength


W(Weight) = - correct answer ✔m×g


How do you compare weights using balance? - correct answer ✔You put a
weight on each side of the balance then whichever way the balance leans is
the heaviest.


What is 'inertia'? - correct answer ✔It is the idea that if a force is applied to
an object, it will not immediately reach a high speed because it requires time
to accelerate, as shown by the formula F=ma.

,Weight (definition) = - correct answer ✔A body's mass multiplied by the
strength of the gravitational field around it.


ρ = - correct answer ✔m×V


Describe an experiment to determine the density of a liquid and of a regularly
shaped solid. - correct answer ✔Find the mass by weighing the object on a
scale and then use a measuring cylinder to find the volume. Then divide the
mass by the volume to get the density in (g/cm³)


Describe the determination of the density of an irregularly shaped solid by the
method of displacement. - correct answer ✔First, fill a Eureka can to the
level of the spout, then lower the solid into the water. Pour the water collected
out of the spout into a measuring cylinder. That is the volume of the solid.
Then, weigh the mass and apply the density formula (ρ = m×V) to calculate
the density.


How do you predict whether an object will float based on density data? -
correct answer ✔Compare the density of the object and the density of the
liquid; if the liquid has a greater density it will float.


A force may produce a change in ____ ___ _____ of a body. - correct answer
✔size and shape


Describe the ways in which a force may change a body. - correct answer ✔a
change in speed, a change in direction, a change in shape


If two or more forces are acting on the same line then the resultant force is
equal to... - correct answer ✔the sum of the forces

, If there is no resultant force on a body it... - correct answer ✔either remains
at rest or continues at constant speed in a straight line


Friction = - correct answer ✔the force between two surfaces which impedes
motion and results in heating


Air resistance = - correct answer ✔a form of friction


State Hooke's Law. - correct answer ✔the force (F) needed to extend or
compress a spring by some distance (e) is proportional to that distance.


F (Hooke's Law) = - correct answer ✔k×e


What is the significance of the 'limit of proportionality' for an extension-load
graph? - correct answer ✔Any extension-load graph must eventually end in a
curve due to the limit of proportionality'.


What is the 'limit of proportionality'? - correct answer ✔when a spring's
extension is not directly proportional to the force used on it anymore.


F = - correct answer ✔m×a


Describe qualitatively motion in a circular path due to a perpendicular force -
correct answer ✔Motion in a circular path happens when a body moves in a
direction while another perpendicular force pulls it inward toward a center. In
electrons this is the electrostatic force that keeps the atoms together; in our
solar system it is the gravity of the sun.
