Basic Concepts Of Biomechanics (1.1 Basic Movement Skills)

Front 1

Motion

Back 1

Newton's laws of motion apply to all movement. In biomechanics, the awareness of body movements can be associated with force, acceleration, and velocity as they relate to maximum effort. The force of energy in the body causes change in physical motion.

Front 2

Newton's first law

Back 2

States that when an object is in motion, it will remain in motion until there is an outside force that acts upon.

Hint 2

For example, when a basketball is thrown toward a basket, there can be a few outcomes. If the ball is thrown using very little strength, the effects of gravity (an outside force) will overcome the velocity of the ball and it will fall short of the basket. If the ball is thrown with too much strength, the ball will overcome the effects of gravity and hit the back board (another outside source) and change its direction.

Front 3

Newton's second law

Back 3

States the relationship between an object's mass, acceleration, and applied force. Continuity of movement is responsible for producing the maximum force and velocity.

Hint 3

To illustrate concept of force:

Upper grade students sit in a chair while trying to throw a basketball into a hoop. students should recognize their inability to follow through with motion. They should then ask the students to throw the basketball when standing up. The force of the entire body in motion should produce an accelerated velocity that results in a force-producing movement to achieve the desired result of the ball reaching the basketball hoop.

Front 4

Newton's third law

Back 4

States that if one object exerts a force in a second object, the second object exerts an equal force on the first object but in the opposite direction. For every action, there is an equal and opposite reaction.

Hint 4

For example:

When a baseball player uses a bat to hit a pitched ball, the force with which the bat hits the ball( and angle) causes the ball to move in an equal and opposite force and direction

Front 5

Gravity

Back 5

The center of The human body can be associated with the "center of gravity. " It is the point around which the mass of the body is equally distributed. The body has a balance base of support and is affected by height, position, and changing movement. During movement and exercise activities, the body adjusts to maintain its stability

Front 6

Friction

Back 6

Friction can be defined as the resistance of motion of two moving objects

Hint 6

For example;

When children play kickball on grass, the ball may move more slowly than when they play kickball on asphalt. There's more resistance because of the friction of the coarse, grassy surfaces
