Biomechanics ( Newtons 3 laws and projectile in motion) Flashcards
What is Newtons first law (The law of Inertia)
Newton’s First Law states that an object at rest stays at rest, and an object in motion stays in motion unless acted upon by an external force
Inertia = the tendency for an object to resist a change in its state of motion.
what is Newtons second law ( The law of Acceleration)
Newton’s Second Law states that the acceleration of an object is directly proportional to the force applied to it
and inversely proportional to its mass.
Meaning a greater force results in greater acceleration, while a larger mass requires more force to accelerate.
Force = Mass x Acceleration
what is Newtons third law (The law of Action and Reaction)
Newton’s Third Law states that for every action, there is an equal and opposite reaction.
This means that when one object exerts a force on another, the second object exerts an equal force back
(e.g., when a swimmer pushes against the wall of a pool, the wall pushes back, propelling them forward).
what is a projectile in motion?
A projectile in motion is an object that follows a trajectory when moving through the air
(e.g., a basketball shot or a javelin throw).
what is height of release?
Height of release is the vertical height from which a projectile is launched or released compared to where it lands. A higher release point can increase the time the projectile stays in the air and affect its overall distance
what is speed of release?
Speed of release is the speed at which a projectile is launched, and it directly affects the distance it travels. A higher speed of release generally results in a greater range (e.g., a soccer ball kicked with more force will travel farther).
what is angle of release
Angle of release is the angle at which a projectile is launched and it influences the trajectory, height, and distance of the projectile.
(e.g., a javelin throw requires an ideal angle for maximum flight distance).
