Newton's Laws of Motion QUIZS

inertia

• The tendency of an object to resist a change in motion.

• The force that causes an object to move in a circular path.

• The speed of an object in a straight line.

• The energy stored in an object due to its position.

Newton's 1st Law of Motion

• An object at rest remains at rest, and an object in motion remains in motion unless acted on by an unbalanced force.

• An object will accelerate in the direction of the net force acting on it.

• For every action, there is an equal and opposite reaction.

• An object in motion will eventually come to a stop without any external force.

external force

• A force acting on an object from the outside.

• A force that is generated within an object.

• A force that opposes motion.

• A force that is always constant.

constant velocity

• Motion in a straight line at a constant speed.

• Motion that varies in speed and direction.

• Motion that occurs only in circular paths.

• Motion that is always accelerating.

Isaac Newton

• Defined the laws of motion and gravity. Tried to explain motion of the universe.

• Developed the theory of relativity and quantum mechanics.

• Invented the telescope and discovered the moons of Jupiter.

• Formulated the laws of thermodynamics and fluid dynamics.

Acceleration

• The rate at which velocity changes.

• The speed of an object in a straight line.

• The distance covered by an object in a given time.

• The force applied to an object.

Newton's 2nd Law of Motion

• The acceleration of an object depends on the mass of the object and the amount of force applied.

• The speed of an object is constant unless acted upon by an external force.

• An object in motion stays in motion unless acted upon by a force.

• The force acting on an object is equal to its mass times its velocity.

Newton's 2nd Law of Motion FORMULA

• Force equals mass times acceleration (F=ma).

• Force equals mass divided by acceleration (F=m/a).

• Force equals acceleration divided by mass (F=a/m).

• Force equals mass plus acceleration (F=m+a).

mass

• The amount of matter in an object measured in grams or kilograms.

• The force exerted by gravity on an object.

• The volume of an object measured in liters or cubic meters.

• The density of an object calculated as mass divided by volume.

Newton's Third Law

• For every action there is an equal and opposite reaction.

• An object in motion stays in motion unless acted upon by an external force.

• The force of gravity is proportional to the mass of the objects involved.

• Energy cannot be created or destroyed, only transformed.
