How does the height of release affect projectile motion
A higher release leads to a greater distance, longer time in the air, and a longer horizontal component
What is the most influential factor affecting projectile motion?
Speed of release.
How does Newton's first law relate to an object in motion?
An object in motion stays in motion at constant velocity unless acted upon by an unbalanced force.
What does Newton's second law state about force, mass, and acceleration?
Acceleration is directly proportional to net force and inversely proportional to mass (F = m*a).
What is the relationship between mass and acceleration in Newton's second law?
If mass remains constant, doubling the acceleration doubles the force needed.
What happens during the action-reaction force in projectile motion?
For every action, there is an equal and opposite reaction (like a racket hitting a ball).
What is the center of mass?
The average position of all parts of a body or system that represents the mean position of the matter.
How does lowering the center of gravity affect stability?
Lowering the center of gravity increases stability, making it harder to topple.
What is the difference between center of mass and center of gravity?
Center of mass is based on mass distribution, while center of gravity considers gravitational force acting on the object.
What defines the base of support?
Areas in contact with the surface that support the body's weight.
What is the line of gravity?
An imaginary line that drops from the center of mass to the base of support.
Describe horizontal projectile motion.
Motion of an object rolling freely along a level surface with constant velocity.
What is vertical projectile motion?
The motion of a freely falling object influenced solely by gravity.
What is parabolic motion?
The path of an object that only accelerates vertically while moving at constant horizontal speed.
How does air resistance affect projectile motion?
Air resistance can slow down an object, making it fall more slowly than if gravity were the only force.
What role does speed play in projectile motion?
Greater speed results in greater distance traveled by the projectile.
What are the two main forces acting on a projectile?
Gravity and air resistance.
How does mass affect air resistance in projectile motion?
Smaller mass and size lead to less influence by air resistance, while heavier objects are more affected by gravity.
