Physical Science Physics - Concept 2

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.
