Questions and Verified for Accuracy Answers
2024/2025
Defined in terms of standards - correct answer base quantity
A physical aspect described by a combination of base quantities -
correct answer derived quantity
The speed of an object in a particular direction - correct answer
Velocity
Change in velocity divided by the time it takes for the change to
occur - correct answer Acceleration
Speeds up
Slows down
And/or
Changes direction - correct answer Acceleration occurs when
an object
A push or pull exerted on an object - correct answer Force
Newton (N) - correct answer SI unit for force
The combination of all forces acting on an object - correct
answer net force
,Forces acting on an object that combine and form a net force of
zero - correct answer balanced forces
Forces that produce a nonzero net force, which changes an
object's motion - correct answer unbalanced forces
(An object continues in uniform motion in a straight line/ at rest
unless a resultant force acts.)
The net force on an object is the cause of its acceleration -
correct answer Newton's First Law
The tendency to keep the same motion- remaining at rest or
maintaining the same velocity - correct answer Inertia
The acceleration of an object depends on the mass of the object
and the amount of force applied.
F=ma - correct answer Newton's Second Law
For every action there is an equal and opposite reaction -
correct answer Newton's Third Law
The force that two surfaces exert on each other when they rub
against each other - correct answer Friction
The force of friction between two objects that are moving against
each other - correct answer kinetic friction
, Frictional force that prevents two surfaces from sliding past each
other - correct answer static friction
A force of attraction between objects that is due to their masses.
- correct answer Gravity
Mass times velocity - correct answer linear momentum
Momentum is conserved when two or more objects collide.
Momentum may transfer but total momentum within the group
stays the same - correct answer Law of conservation of
momentum
The ability of a material to bounce back after being disturbed -
correct answer Elasticity
Force exerted on an object that causes it to move - correct
answer Work
The ability to do work or cause change - correct answer Energy
Energy of motion - correct answer kinetic energy
Energy that is stored and held in readiness - correct answer
potential energy
Force x distance - correct answer Work formula
