Question

what is the unit of force in physics?
newtons
torque
kilograms
mass

Explanation:

• Newtons: In physics, force is calculated using the formula \(F = ma\) (where \(F\) is force, \(m\) is mass, and \(a\) is acceleration). The SI unit for force is named after Sir Isaac Newton, and it is defined as \(1\space N= 1\space kg\cdot m/s^{2}\).
• Torque: Torque (\(\tau\)) is a rotational force and is calculated as \(\tau=r\times F\) (where \(r\) is the lever - arm distance and \(F\) is the force). Its unit is \(N\cdot m\) (Newton - meter), which is different from the unit of force.
• Kilograms: Kilogram (\(kg\)) is the SI unit of mass, not force.
• Mass: Mass is a physical quantity, and its SI unit is the kilogram. It is not a unit of force.

Answer:

newtons
