projectile motion

Question 1

What is benoullis principle upward lift?

Answer 1

an upward lift force is when the curved surface of the object has a higher velocity and lower pressure. the other side that has a higher pressure and lower velocity wikl always meet the other side at the same time.

Question 2

What is bernoullis principle? upward

Answer 2

Theory of how an additional lift force is created during flight based on the shape of the projectile

Question 3

What is the lift force?

Answer 3

Additional force created from pressure gradients forming on opposite surfaces of an aero foil moving through liquid (acts perpendicular to the range of motion)

Question 4

What is the affect of an upward lift force?

Answer 4

Increases potential flight time of a projectile and therefore the horizontal distance travelled

Question 5

On benoullis upward where are the lines closer?

Answer 5

at the curved surface (top)

Question 6

what is the angle of attack?

Answer 6

Most favourable angle of release of a projectile to optimise lift force to increase flight time and horizontal distance

Question 7

What is an aerofoil?

Answer 7

streamlined shape with a curved upper surface and flat lower surface

Question 8

what is the resultant force diagram?

Answer 8

weight force arrow smaller than fbd due to the lift force making object feel light below
