• Muscles in the body

• Gravity

• None of the above

Which of the following is Newton's 2nd Law of Motion

• An object at rest tends to stay at rest

• Inertia

• For every action there is a reaction

• F = ma

The lower the centre of mass the greater the stability

• True

• False

Which of the following describes a second class lever

• Fulcrum in between the load and effort

• Effort in between the fulcrum and the load

• None of the above

The phases of movement include

• Preliminary movements

• Force Production

• Critical instance

• All of the above

A force that acts through the centre of mass results in

• Linear motion

• Angular motion

• General motion

• All of the above

A measure of the force that can cause an object to rotate about an axis is

• Angular Motion

• Torque

• Moment Arm

• Inertia

The application of an external force over a short period of time is known as

• Inertia

• Mass

• Impulse

• Impact

Which principle explains the behavior of a spinning object when an external torque acts on it?

• Newton's First Law of Motion

• Conservation of Angular Momentum

• Gyroscope Principle

• Law of Conservation of Energy

What is the effect of an unbalanced force acting on an object?

• It will change the object's shape

• It will cause the object to accelerate

• It will not affect the object

• It will make the object lighter
