Inertia
is the rate of change of an object's position
determines that rate of angular velocity
is the resistance of a body to change its state of motion
is directly proportional to velocity
According to Newton's 2nd law of motion, the acceleration of an object is proportional to (a) and
(b)
In this image the forces are equal and opposite. What will happen to the bat upon impact?
(a)
This image represents which class lever?
1st class lever
2nd class lever
3rd class lever
This image represents which class lever?
1st class lever
2nd class lever
3rd class lever
A sprinter is able to accelerate from the blocks due to a combination of:
friction and air resistance
weight and friction
internal force and friction
internal force and gravity
Which letter has been labelled incorrectly in the diagram?
R
F
W
AR
Stability:
Refers to the degree to which a body resists changing its equilibrium.
Is impacted by height and line of the centre of gravity.
Is impacted by the size of the base of support.
Is impacted by the mass of an object and friction between bodies.
Is impacted by the friction between to objects. eg a rugby player would use boots with long stops in them to increase friction and thus stability.
Which of the following will change if you lift your arms above your head?
Axis of rotation
Base of Support

Which of the following will decrease stability?
Lowering COM
Increasing the base of support
Reducing the number of points of contact.
Wearing studs on grass.
