Vocabulary
It is recognized as an action exerted on a body in order to change the body's state of rest or motion.
What is force?
This law states that an object remains at rest unless an external object inflicts force upon it.
What is Newton's first law of motion?
What is friction?
A ball thrown up in the air will not change direction unless an external force (like the wind) acts upon it.
What is Newton's first law?
A force that resists sliding motions between two surfaces that are in contact + at rest.
What is static friction?
This is the tendency for an object to resist changes in motion unless an outside force acts on the object.
What is inertia?
This law states that when an object exerts force on another object, the second object exerts an equal and opposite force on the first.
What is Newton's third law of motion?
He invented calculus in the 1600s and the universal theory of gravity.
Who is Sir Isaac Newton?
Racecars are usually attempted to be kept low in mass.
What is Newton's second law?
The ratio of friction of objects before sliding to normal force.
Recognized as a state of balance; in physics, it is when the net force of an object is zero
What is equilibrium?
This law states that the acceleration of an object depends on the amount of force and mass of the object.
What is Newton's second law of motion?
The symbol net force is represented by.
What is sigma (Ʃ)?
A book lying on top of a table will not move unless picked up or moved.
What is Newton's first law?
A force that opposes movement of surfaces sliding over each other and in contact.
What is kinetic friction?
A force whose external effects on a rigid body are the same as the effects of several actual forces acting on said body.
What is net force?
The acceleration of an object is directly proportional to the net force acting on the object and inversely proportional to the object’s mass.
What is Newton's second law of motion?
It is a vector quantity because it has magnitude and direction.
What quantity is force?
When on a boat/ship, the propellor pushes the water to move the boat, and the water pushes an equal and opposite force back against the propellor.
What is Newton's third law?
A force that acts perpendicular to a surface.
What is the normal force?
A measure of gravitational force exerted on an object that changes depending on where in the universe said object is located.
What is weight?
"For every action, there is an equal and opposite reaction."
What is Newton's third law of motion?
The forces two objects exert on each other.
What are action-reaction pairs?
When a baseball is sent flying by a bat, it exerts a force on the bat, as does the bat against the baseball.
What is Newton's third law?
It is defined to be the mass of an object times its velocity.
What is momentum?
