Questions and Answers with Verified
Solutions
Question 1:
distance
Answer:
The length of a path between two points
Question 2:
Displacement
Answer:
Distance and direction of an object's change in position from the starting
point.
Question 3:
position
Answer:
the location of an object
Question 4:
Speed
Answer:
The distance an object travels per unit of time
,Question 5:
Acceleration
Answer:
The rate at which velocity changes
Question 6:
instantaneous speed
Answer:
the speed of an object at one instant of time
Question 7:
Force
Answer:
A push or pull on a object
Question 8:
net force
Answer:
The combination of all forces acting on an object
Question 9:
constant speed
Answer:
Speed that does not change
, Question 10:
average speed
Answer:
total distance divided by total time
Question 11:
Newton's first law ( Aka Law of Inertia)
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.
Question 12:
Newton's Second Law
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.
Question 13:
Newton's Third Law
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.
