Hint

1

what is the composition of the position vector (r)?

New cards

2

average velocity

the difference of the position vectors divided by the time vectors.

3

instantaneous velocity vector projectile is any body that is given an initial velocity and then follows a path determined entirely by the effects of gravitational acceleration and air resistance.

it is the limit of the average velocity as the time interval approaches zero, and it equals the instantaneous rate of change of position with time.

5

trajectory of a projectile

The path followed by a projectile is called its trajectory

formula for a(rad) with uniform acceleration

The formula for acceleration in uniform circular motion is `a = v^2/r`

, where `a`

is the acceleration, `v`

is the velocity, and `r`

is the radius of the circular path.
