The equation for Hooke's Law is as follows:

$F_s=-kx$

$F_s$ is the displacement of the spring from its equilibrium position.

True
False

Grade 11 Forces and Motion

When an object falls in a medium, such as air, it will reach a terminal velocity. How fast it reaches terminal velocity and the value of that terminal velocity depends on properties of the medium and

the mass of the falling object.
the weight of the falling object.
the size of the falling object.
the shape of the falling object.

Grade 11 Mechanics

The iconic World War two British fighter, the Spitfire was unusual in having a large wing area compared to similar aircraft. This allowed it to have a greater force of lift. If the wing area was 22.5m^2, its top speed was 158 m/s, the air density is 0.88kg/m^3, and the co-efficient of lift 0.12. This lift was 5.93.10^4 N.

True
False

$1.2 \ m^3//s$
$33.3 \ m^3//s$
$0.030 \ m^3//s$
$12.0 \ m^3//s$
