Identify Newton's 1st Law.
An object at rest stays at rest and an object in motion stays in motion unless acted upon by an external force.
Force equals mass times acceleration.
For every action, there is an equal and opposite reaction.
Energy cannot be created or destroyed.
Identify Newton's 2nd Law.
An object at rest will stay at rest until acted on by an external force
F = m*a
For every action force, there is an equal and opposite reaction force.
The more mass an object has, the stronger its gravitational force.
Identify Newton's 3rd Law.
For every action, there is an equal and opposite reaction.
An object at rest stays at rest, and an object in motion stays in motion.
Force equals mass times acceleration.
Energy cannot be created or destroyed.
Define Terminal velocity.
Terminal velocity is the constant speed that an object eventually reaches when falling through a fluid (such as air or water). It occurs when the force of gravity is balanced by the drag force acting against the object's motion, resulting in no further acceleration.
Terminal velocity is the speed at which an object starts accelerating when falling through a fluid.
Terminal velocity is the speed at which an object stops moving when falling through a vacuum.
Terminal velocity is the speed at which an object starts moving upwards when falling through a fluid.
Define Friction.
Friction is a force that opposes the relative motion or tendency of such motion of two surfaces in contact.
Friction is a type of energy that is stored in objects.
Friction is the force that causes objects to move faster.
Friction is the process of objects sticking together.
Define Force.
Force is an interaction that, when unopposed, will change the motion of an object. It can be described as a push or pull on an object resulting from the object's interaction with another object.
Force is a type of energy that is stored in an object and can be released to do work.
Force is a measure of the amount of matter in an object, usually measured in kilograms.
Force is the ability of an object to resist changes in its state of motion.
Define Field.
Field is a term used in various contexts, often referring to a specific area of study, a physical space, or a set of data attributes in a database.
Field is a type of plant found in tropical regions.
Field is a brand of electronic gadgets.
Field is a type of musical instrument.
Define Inertia.
Inertia is the property of an object to resist changes in its state of motion. It is a measure of an object's mass and is directly related to the object's tendency to remain at rest or in uniform motion unless acted upon by an external force.
Inertia is the force that causes objects to move in a circular path.
Inertia is the energy required to change the temperature of an object.
Inertia is the ability of an object to conduct electricity.
Define Balanced forces.
Balanced forces are forces that are equal in size, but opposite in direction. When balanced forces act on an object, they do not cause a change in the object's motion.
Balanced forces are forces that are unequal in size and act in the same direction, causing a change in the object's motion.
Balanced forces are forces that are equal in size and act in the same direction, causing acceleration.
Balanced forces are forces that are unequal in size and opposite in direction, causing the object to move.
Define Centripetal force.
Centripetal force is the force that acts on an object moving in a circular path, directed towards the center of the circle around which the object is moving.
Centripetal force is the force that acts on an object moving in a straight line, directed away from the center.
Centripetal force is the force that acts on an object at rest, directed towards the center of the Earth.
Centripetal force is the force that acts on an object moving in a circular path, directed away from the center of the circle.
Which is the definition for gravity?
Gravity is a natural phenomenon by which all things with mass or energy are brought toward one another, including objects ranging from atoms to planets and light beams.
Gravity is a force that only affects objects with a large mass, like planets.
Gravity is a phenomenon that only occurs on Earth and nowhere else in the universe.
Gravity is a type of magnetism that only affects metal objects.
Define Net force.
Net force is the vector sum of all the individual forces acting on an object. It determines the object's acceleration according to Newton's second law of motion.
Net force is the scalar sum of all the individual forces acting on an object.
Net force is the difference between the largest and smallest forces acting on an object.
Net force is the force required to keep an object at rest.
Which is the definition for weight?
The amount of gravitational force exerted on an object.
A measure of the amount of matter in an object.
The combination of all the forces acting on an object.
The forces on an object with a net force of zero.
Which is the definition for mass?
The amount of gravitational force exerted on an object.
A measure of the amount of matter in an object.
The combination of all the forces acting on an object.
The forces on an object with a net force of zero.
What happens to acceleration when force is increased?
Acceleration decreases
Acceleration remains the same
Acceleration increases
Acceleration becomes zero
When a falling object reaches terminal velocity, what is the relationship between the force of gravity and the force of air resistance?
The force of gravity is greater than the force of air resistance.
The force of gravity is less than the force of air resistance.
The force of gravity is equal to the force of air resistance.
There is no relationship between the two forces.

Newton's First Law
Law of Conservation of Momentum
Newton's Third Law
Law of Universal Gravitation
