Newtons Laws Flashcardizz

Front

What is inertia?

Back

Inertia is the property of an object to resist changes in its state of motion. An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is thrust?

Back

Thrust is the force generated by an engine or a propeller that propels an object forward. It is a key concept in understanding how vehicles and aircraft move.

Front

What does the law of inertia state?

Back

The law of inertia states that an object will remain at rest or in uniform motion in a straight line unless acted upon by a net external force.

Front

What does a bathroom scale measure?

Back

A bathroom scale measures the normal force exerted by the ground on a person standing on it, which is equal to the gravitational force acting on the person.

Front

What happens to the acceleration of a ball rolling down a ramp?

Back

The acceleration of a ball rolling down a ramp increases due to the force of gravity acting on it, assuming no friction.

Front

What is gravitational force?

Back

Gravitational force is the attractive force between two masses. It is proportional to the product of the masses and inversely proportional to the square of the distance between their centers.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, measured in kilograms, while weight is the force exerted by gravity on that mass, measured in newtons.

Front

What is applied force?

Back

Applied force is a force that is applied to an object by a person or another object. It can cause an object to move or change its motion.

Front

What is normal force?

Back

Normal force is the support force exerted upon an object that is in contact with a surface. It acts perpendicular to the surface.

Front

What is friction force?

Back

Friction force is the force that opposes the relative motion of two surfaces in contact. It acts parallel to the surfaces.
