complete solution 2025/2026
distance - correct answer ✔The length of a path between two points
Displacement - correct answer ✔Distance and direction of an object's change in position from the
starting point.
position - correct answer ✔the location of an object
Speed - correct answer ✔The distance an object travels per unit of time
Acceleration - correct answer ✔The rate at which velocity changes
instantaneous speed - correct answer ✔the speed of an object at one instant of time
Force - correct answer ✔A push or pull on a object
net force - correct answer ✔The combination of all forces acting on an object
constant speed - correct answer ✔Speed that does not change
instantaneous speed - correct answer ✔the speed of an object at one instant of time
average speed - correct answer ✔total distance divided by total time
, Newton's first law ( Aka Law of Inertia) - correct answer ✔"An object at rest remains at rest, and an
object in motion will remain in motion unless acted upon by some external net force."
A rock for example will remain at rest, it won't start spontaneously moving. An object in motion, that
does not encounter any friction will keep moving, like an object floating in space.
Newton's Second Law - correct answer ✔Force = mass x acceleration ( F=ma)
To find acceleration: A= F/ m
" the acceleration an object experiences is directly proportional to the applied force and inversely ( in
the opposite manner) proportional to its mass.
Newton's Third Law - correct answer ✔For every action there is an equal and opposite reaction.
As a car hits a wall, it's force is applied to the wall but the force of the wall also acts on the car.
Remember, there can never be a single isolated force, forces always come in pairs.
coefficient of friction - correct answer ✔the ratio of the force of friction to the normal force acting
between two objects. When you find a coefficient of friction, you're calculating the resistance to motion
at the interface of two surfaces of similar or dissimilar materials.
( a brick sliding on a clean wooden table, the coefficient of kinetic friction is about 0.5)
Torque - correct answer ✔a turning or twisting force. Represented by T
Formula: T=Fd
