Chapter 4- Kinematic concepts of human movement

Which of the following is NOT an aspect of linear motion?

• How far a body moves

• How fast a body moves

• How well a body spins

• How consistently a body moves

What is distance?

• The path a body takes as it moves from one location to another

• The path of a body as it moves in a straight line

• The rate at which a body moves from one location to another

• The rate at which the speed of a body changes with time

What is positive acceleration?

• When speed is increasing to the left

• When speed is increasing to the right

• When velocity is decreasing

• When velocity is increasing

Which of the following does NOT represent a projectile?

• A pitched softball

• A sprinter crossing a finish line

• A thrown javelin

• A kicked soccer ball

The 'time in flight' of a body is equal to which of the following?

• Trajectory up- trajectory down

• Horizontal distance- vertical distance

• Trajectory up + trajectory down

• Horizontal distance + vertical distance

Which of the following represents the ideal angle of projection for a long jumper?

• 60-68 degrees

• 5-10 degrees

• 40-48 degrees

• 18-27 degrees

What is angular displacement?

• The angle between the initial and final positions of the body

• The exact length of the body's angular path

• The angular distance- time taken

• Time taken + angular distance

Which of the following is NOT a means of increasing the distance of a kick in soccer?

• Increasing the angular velocity of the leg as it strikes the ball

• Extending the knee joint at the point of impact

• Decreasing the backswing of the leg

• All of the above

What is general motion?

• Motion of the body as a whole

• A combination of linear and angular motion

• The combined motion of all body parts involved in an action

• Any motion in a forward or backward direction

Which of the following is an example of general motion?

• Swimming

• Kicking a football

• Throwing a softball

• Shooting a netball
