Projectile Motion

Question 1

projectile

Answer 1

a body whose motion is subject only to the forces of gravity and fluid resistance

Question 2

what is the acceleration of a projectile

Answer 2

-9.81m/s2

Question 3

what other force besides gravity acts on a projectile

Answer 3

resistance of the fluid medium through which it is moving
is often ignored

Question 4

trajectory

Answer 4

the flight path of the center of gravity of a projectile

Question 5

what affects trajectory

Answer 5

projection velocitty
projection angle
relative projection height

Question 6

projection velocity

Answer 6

velocity at release
affects the length and height of trajectory

Question 7

projection angle

Answer 7

the angle at which the object is projected
affects the shape of the trajectory

Question 8

relative projection height

Answer 8

difference between the height of release and the height of impact
the greater the relative projection height, the longer the flight time of the projection

Question 9

law of uniformly accelerated motion

Answer 9

relate acceleration, displacement, time, and velocity in the condition of a constant gravitational acceleration
