PHYSICS: AIR RESISTANCE

What is the zenith?

The maximum height/top of curve of a projectile

What is range?

The horizontal displacement

What angle gives the maximum range from the ground and why?

45 degrees as it is in the middle of the horizontal and vertical components of velocity.

Do complements of an angle give the same range?

yes

What does air resistance reduce?

vertical and horizontal components of velocity. Therefore reduces height, time and range.

From a higher platform, will a reduced angle produce a greater range

Yes, from 42 degrees to 44 degrees is beneficial

What is the equation for drag?

What does the D stand for in the drag equation?

drag coefficient, it is a constant value

What does the A stand for in the drag equation?

cross-sectional area. It is a variable

What does the P stand for in the drag equation?

density of air, it is a given constant value

What does the V stand for in the drag equation?

The speed

Air resistance will oppose what??

the vertical component of velocity

What is drag directionally proportional to?

V squared and A

Does time increase or decrease from the effect of air resistance?

Decrease. It heavily decreases the first half of the parabola. It increases slightly on the second half of the parabola. Overall time is still reduced.

Does horizontal velocity use cos or sin?

cos

Does vertical velocity use cos or sin?

sin
