Newtons Laws Flashcardizz

Front

What is the relationship between weight and mass on different celestial bodies?

Back

Weight is the force of gravity acting on an object, which varies depending on the gravitational pull of the celestial body. Mass remains constant regardless of location.

Front

What factors affect the amount of friction between two surfaces?

Back

The weight of the object, the materials of the surfaces in contact, and the irregularities in the surfaces all affect the amount of friction.

Front

What is thrust in the context of forces?

Back

Thrust is the force generated by an engine or propeller that propels an object forward.

Front

In which direction does friction act in relation to an object's motion?

Back

Friction always acts opposite to the direction of the object's motion.

Front

What is inertia?

Back

Inertia is the property of an object to resist changes in its state of motion. It is directly related to the mass of the object.

Front

How does mass affect gravitational force?

Back

The gravitational force between two objects increases with greater mass and decreases with greater distance between them.

Front

What is the formula for calculating weight?

Back

Weight (W) = mass (m) × gravitational acceleration (g). On Earth, g is approximately 9.81 m/s².

Front

What is the difference between static and kinetic friction?

Back

Static friction acts on an object at rest and prevents it from starting to move, while kinetic friction acts on an object that is already in motion.

Front

What is the principle of action and reaction in Newton's Third Law?

Back

For every action, there is an equal and opposite reaction. This means that forces always occur in pairs.

Front

How does surface area affect air resistance?

Back

Increased surface area generally increases air resistance, as there is more area for air molecules to collide with the object.
