  • How many dynes are equivalent to one newton?: One newton is equivalent to 100,000 dynes (10⁵ dyn). The dyne is the unit of force in the centimeter-gram-second (CGS) system.

What is the approximate force exerted by a 62 kg adult on Earth's surface?

Answer: 608 N

A 62 kg adult experiences a force (weight) of approximately 608 Newtons on Earth's surface, calculated as mass (62 kg) multiplied by the standard acceleration due to gravity (9.80665 m/s²).

  • What is a kilonewton (kN), and how does it relate to a newton?: A kilonewton (kN) is a unit of force equal to 1,000 Newtons. It is commonly used for expressing larger forces, such as the tractive effort of locomotives or the thrust of jet engines.
  • What is the approximate force exerted by an average adult on Earth's surface?: An average adult, estimated to have a mass of 62 kilograms, exerts a force of approximately 608 Newtons on Earth's surface. This is calculated as 62 kg multiplied by the standard acceleration due to gravity (9.80665 m/s²).

What is the SI unit of torque, and how is it derived from the Newton?

Answer: Newton meter (N⋅m), defined as force times distance.

The SI unit of torque is the Newton meter (N⋅m), which is derived from the product of force (Newton) and distance (meter).
