Question 1

A person is completing a maximal voluntary isometric contraction and the researcher needs to resist joint motion, how do you do this?

Answer 1

Match the angle that the isometric contraction is at

Question 2

If a pinwheel rotates a full circle, its angular displacement would be

Answer 2

0
-does a full rotation, returns to where it started

Question 3

Arc length=

Answer 3

Arc length (L) = THETA (angle) x radius

Question 4

How does tangential velocity change according to the radius of the rotating object?

Answer 4

The further you are from the centre, the faster the velocity will be
So, the greater the radius, the greater the tangential velocity

Question 5

Total Energy is equal to

Answer 5

Kinetic Energy and Potential Energy

Question 6

Why does walking in heels generally hurt more than walking in normal shoes

Answer 6

They have less contact with the ground, lesser area when placed down
Pressure= force/ area
-so with less area, the pressure would be higher
