PAPER VERIFIED SOLUTIONS
◉ Velocity. Answer: refers to speed in a specific direction
◉ Scalar Quantity. Answer: quantity described simply by a numeric
value and is expressed in units of magnitude
◉ Vector Quantity. Answer: quantity describing the time rate of change
of an object's position and must be expressed in both units of magnitude
and direction of motion
◉ Average Velocity. Answer: determined by averaging the initial speed
and the final speed of the object
◉ Acceleration. Answer: the rate of change in velocity over a period of
time
◉ Projectile Motion. Answer: it is possible for an object to display two
types of motion simultaneously
◉ Force. Answer: defined as a push or a pull on an object
, ◉ Newton's First Law of Motion. Answer: states that the body at rest
will remain at rest, and the body in motion will remain in motion with a
constant velocity, unless acted on by an unbalanced force; F=ka
◉ Newton's Second Law of Motion. Answer: the constant of
proportionality is equal to the mass of the object; F=ma
◉ Newton (N). Answer: the unit of force and is equal to the force
necessary to accelerate a mass of one kilogram one meter per second per
second
◉ Newton's Third Law of Motion. Answer: states that for every action
there must be an equal and opposite reaction
◉ Friction. Answer: a force that opposes motion and is expressed in
newtons
◉ Centripetal Acceleration. Answer: rotational motion equivalent of
acceleration
◉ Kinetic Energy. Answer: the energy resulting from the motion of the
object
◉ Potential Energy. Answer: the energy the object has because of its
position
