Kinetic Concepts

The term used to describe forces that are directly associated with causing motion is;

• Momentum

• Kinematic Concepts

• Kinetic Concepts

• Motion

A 100m sprint is an example of which type of motion?

• Friction

• Force

• Angular

• Linear

Angular Motion is;

• When a body rotates around an axis

• Occurs in a straight line or curved path

• When there is contact on the surfaces of two objects

• The reluctance of a body to move

Which types of forces are needed to overcome something's inertia?

• Friction

• Push

• Gravity

• Pull

What is equation for force?

• Mass x Velocity

• Mass x Acceleration

• Velocity x Acceleration

• Velocity x Movement

Something with a really high inertia is typically;

• Very hard to move

• Very easy to move

• Impossible to move

• Never seen in sport

In order for a rugby player to complete a tackle, they need to overcome their opponent's inertia. How do they do this?

• Don't apply as much force

• Only use their arms

• Apply more force to overcome the opponent's inertia

• Have good stability

In a game of basketball, the centre (96kg) collides with the opposition small forward (85kg). After the impact, it is the centre that falls back and over onto the ground, while the SF is able to keep their feet. How is it possible that the SF had a higher momentum in this scenario? (Remember: Momentum = Mass x Velocity)

• C had little inertia

• SF was moving at a much higher velocity

• C has a higher mass

• SF has a higher mass

Summation of Momentum refers to;

• Gaining mass to create more force

• Moving at a faster velocity to create more force

• Force over time

• Adding multiple body parts to a movement in order to create more force

A gymnast bending their knees as they land from a jump is an example of impulse, where they are; (remember; impulse = force over time)

• Overcoming inertia

• Increasing force over time

• Decreasing force over time

• Increasing momentum
