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.

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.

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.
