Biomechanic Basics
Define biomechanics.
The study of forces and their effects on the human body in movement.
What does Newton’s First Law state?
An object at rest stays at rest, and an object in motion stays in motion unless acted upon by an external force (Law of Inertia).
What is the difference between distance and displacement?
Distance is the total path traveled, while displacement is the shortest straight-line distance from start to finish.
Who is the most followed person on tiktok?
Khabane Lame
What is the difference between speed and velocity?
Speed is the rate of motion regardless of direction, while velocity includes both speed and direction.
Provide an example of Newton’s Second Law in sports.
A baseball hit with more force will accelerate faster and travel farther (Force = Mass × Acceleration).
How do mass and weight differ?
Mass is the amount of matter in an object (kg), while weight is the force due to gravity acting on mass.
Who was the last NFL franchise to make it to 3 straight super bowls?
Patriots
How does mass affect momentum?
Momentum is calculated as mass × velocity. An object with more mass has greater momentum if moving at the same velocity as a smaller object.
How does Newton’s Third Law explain jumping?
What is the optimal angle to release an object in projectile motion?
The angle of release affects how far and how high an object travels; 45° typically maximizes distance.
What is the highest grossing app on the app store?
Youtube
What is impulse, and why is it important in sports?
Impulse is the change in momentum caused by a force applied over time. In sports, increasing impulse (e.g., following through in a swing) can generate more power.
A soccer player kicks a ball with 50 N of force. If the ball has a mass of 0.5 kg, what is its acceleration?
100 m/s²
Compare and contrast momentum and impulse.
Momentum (mass × velocity) describes motion, while impulse (force × time) changes momentum. Impulse can increase or decrease an object’s motion, such as in catching a ball or pushing off in a sprint.
What is the highest grossing movie of 2025?
Captain America: Brave New World
