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.

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.

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.

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.

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.

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.

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.

Front

What is applied force?

Back

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

Front

What is buoyant force?

Back

Buoyant force is the upward force exerted by a fluid on an object submerged in it. It counteracts the weight of the object and is responsible for the phenomenon of floating.

Front

What is thrust?

Back

Thrust is the force that propels an object forward, typically produced by engines or propellers. It is essential for the movement of vehicles such as airplanes and rockets.
