Projectiles
This is the force that causes an object to return to the ground.
What is gravity.
This quantity is defined as force applied over a distance in the direction of motion.
what is work
the force that acts in the opposite direction of motion between two objects in contact
what is friction
What is Newton's 1st law?
What is an object in motion stays in motion unless acted upon by an outside force.
This is the acceleration due to gravity near Earth.
What is 9.81 m/s/s
What component of a projectile's velocity changes due to gravity?
What is the vertical component
This form of energy is associated with the motion of an object.
what is kinetic energy
This type of friction acts on an object that is moving relative to another surface.
What is Newton's 3rd law?
What is for every action there is an equal and opposite reaction.
In this type of motion, an object only experiences gravity acting on it.
What is free fall?
When launched off of a cliff, what factor determines how long a projectile will stay in the air?
What is the initial vertical position?
This equation is used to calculate gravitational potential energy near Earth’s surface.
what is PE=mgh
This kind of friction prevents an object at rest from starting to move.
what is static friction
What is Newton's second law?
What is F=ma
What is it becomes 1/4 as large
What angle of launch provides the maximum horizontal range for a projectile?
What is 45 degrees?
This quantity measures how quickly work is done or energy is transferred.
what is power
This value is represents the coefficient of friction between 2 surfaces.
What is mu?
What everyday object is equal to one Newton?
What is an apple.
This equation is used to calculate gravitational forces between 2 objects.
F=Gm1m2/r^2
If a projectile is fired horizontally, and at the same time another is dropped straight down from the same height, which will hit the ground first?
What is they will both hit the ground at the same time?
This principle states that energy cannot be created or destroyed, only transformed from one form to another.
What is the Law of Conservation of Energy.
What is the coefficient of kinetic friction between rubber on ice.
What is 0.15?
Who did Isaac Newton ALLEGEDLY burn the painting of?
Who is Robert Hooke?
What is the gravitational constant on the moon?
