What is Linear Motion?

• Motion in a straight or curved line where all body parts move in the same direction simultaneously.

• Motion around an axis of rotation.

• Combination of linear and angular movements.

What is Angular Motion?

• Motion in a straight or curved line.

• Motion around an axis of rotation where body parts move in a circular path.

• Combination of linear and angular movements.

General Motion is a combination of ______ and angular movements.

What does mass measure?

• The force a body exerts due to gravity's pull

• The amount of matter in a body

• The gravitational field strength

• The acceleration of an object

Mass is measured in _______.

Weight is calculated using the formula W = mg. What does 'g' represent in this formula?

• Mass

• Gravitational acceleration

• Force

• Matter

What does inertia resist?

• Motion

• Change in motion

• Force

• Gravity

Heavier athletes require more force to tackle because:

• they have more mass, which increases inertia.

• they are more agile and quick.

• they have better technique.

• they are more experienced.

What is the formula for Force?

• F = ma

• F = mv

• F = m/v

What is the formula for Torque?

• Torque = force × lever arm

• Torque = force / lever arm

• Torque = force + lever arm

• Torque = force - lever arm
