100
Flight path of a projectile.
What is trajectory?
100
the center of balance of an object.
What is center of gravity?
100
A body will remain in its state of rest or uniform motion until an outside force changes its state
What is Newton's First Law-Law of Inertia.
100
the amount of substance of an object
What is mass?
200
Optimal projection angle for maximal range.
What is 45 degrees?
200
area bound by the outermost regions of contact between a body and the support surface
What is base of support?
200
The greater the force, the greater the acceleration. The smaller the mass, the greater the acceleration.
What is Newton's 2nd Law-Law of Acceleration.
200
speeding up or slowing down.
What is acceleration?
200
Mass x Velocity
What is momentum?
300
The highest point that a projectile reaches in it's flight path.
What is apex?
300
resistance to disruption of equilibrium
What is stability?
300
For every action there is an equal and opposite reaction.
What is Newton's 3rd Law-Law of Reaction.
300
the speed of an object and its direction.
What is velocity?
300
displacement/time
What is velocity?
400
ability to control equilibrium
What is balance?
400
The difficulty to get a stationary object moving or to stop an in-motion object. (term)
What is inertia?
400
A change in position.
What is displacement?
400
Change in angular velocity/time
What is angular acceleration?
500
List 3 things that affect the trajectory of a projectile.
What is height of release, speed of release, angle of release?
500
List 2 ways of increasing stability.
What is widening base of support, placing weight closer to outside force.
500
A force that prevents movement away from the earth.
What is gravity?
500
Force x distance
