FLASHCARD QUESTION

Front

What is a free body diagram?

Back

A free body diagram is a graphical representation used to visualize the forces acting on an object. It shows all the external forces acting on the body, allowing for analysis of the object's motion.

FLASHCARD QUESTION

Front

What is weight force?

Back

Weight force is the force exerted on an object due to gravity. It is calculated using the formula: Weight (W) = mass (m) × gravitational acceleration (g), where g is approximately 9.81 m/s² on Earth.

FLASHCARD QUESTION

Front

How do you determine which object has more weight force?

Back

To determine which object has more weight force, compare their masses. The object with the greater mass will experience a greater weight force, as weight is directly proportional to mass.

4.

FLASHCARD QUESTION

Front

What is the normal force?

Back

The normal force is the force exerted by a surface to support the weight of an object resting on it. It acts perpendicular to the surface and balances the weight force when the object is at rest.

FLASHCARD QUESTION

Front

What is frictional force?

Back

Frictional force is the force that opposes the relative motion of two surfaces in contact. It acts parallel to the surfaces and can vary depending on the nature of the surfaces and the normal force.

FLASHCARD QUESTION

Front

What unit is used to measure force in the International System of Units (SI)?

Back

The unit used to measure force in the SI system is the Newton (N). One Newton is defined as the force required to accelerate a one-kilogram mass by one meter per second squared.

FLASHCARD QUESTION

Front

What is gravitational force?

Back

Gravitational force is the attractive force between two masses. On Earth, it is the force that pulls objects toward the center of the planet, commonly referred to as weight.
