answers

Average Speed - CORRECT ANSWERS ✔✔the distance an
|\ |\ |\ |\ |\ |\ |\ |\



object travels divided by the time the object travels
|\ |\ |\ |\ |\ |\ |\ |\ |\



without regard to direction of travel
|\ |\ |\ |\ |\ |\




average speed = d/t |\ |\ |\




Velocity - CORRECT ANSWERS ✔✔refers to speed in a
|\ |\ |\ |\ |\ |\ |\ |\ |\



specific direction |\




Scalar Quantity - CORRECT ANSWERS ✔✔quantity
|\ |\ |\ |\ |\ |\



described simply by a numeric value and is expressed in
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\



units of magnitude
|\ |\




Vector Quantity - CORRECT ANSWERS ✔✔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 - CORRECT ANSWERS ✔✔determined by
|\ |\ |\ |\ |\ |\ |\



averaging the initial speed and the final speed of the
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\



object

, Acceleration - CORRECT ANSWERS ✔✔the rate of change |\ |\ |\ |\ |\ |\ |\ |\



in velocity over a period of time
|\ |\ |\ |\ |\ |\




Projectile Motion - CORRECT ANSWERS ✔✔it is possible
|\ |\ |\ |\ |\ |\ |\ |\



for an object to display two types of motion
|\ |\ |\ |\ |\ |\ |\ |\ |\



simultaneously


Force - CORRECT ANSWERS ✔✔defined as a push or a pull
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\



on an object
|\ |\ |\




Newton's First Law of Motion - CORRECT ANSWERS |\ |\ |\ |\ |\ |\ |\ |\



✔✔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 - CORRECT ANSWERS |\ |\ |\ |\ |\ |\ |\ |\



✔✔the constant of proportionality is equal to the mass of
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\



the object; F=ma
|\ |\




Newton (N) - CORRECT ANSWERS ✔✔the unit of force and
|\ |\ |\ |\ |\ |\ |\ |\ |\



is equal to the force necessary to accelerate a mass of
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\



one kilogram one meter per second per second
