So what is the force in Newtons?

In summary, force is the interaction that causes a change in an object's motion and is measured in units called Newtons (N). It is calculated by multiplying an object's mass by its acceleration and can be converted from other units using conversion factors. The force of gravity is also measured in Newtons by multiplying an object's mass by the acceleration due to gravity. According to Newton's Second Law of Motion, force is directly proportional to an object's acceleration, making the unit of Newtons a measure of an object's ability to accelerate.

To find the force of gravity on the mass, apply Newton's 2nd law. What's the acceleration due to gravity?

The force in Newtons can be calculated using Newton's Second Law of Motion, which states that force is equal to mass multiplied by acceleration. In this scenario, the mass is given as 100kg and the body is freely falling, meaning it is accelerating at a rate of 9.8 m/s^2. Therefore, the force in Newtons can be calculated as 100kg x 9.8 m/s^2, which equals 980 Newtons. This is the force acting on the body due to gravity as it falls.
 

1. What is the definition of force in Newtons?

Force is defined as any interaction that causes a change in the motion of an object. In the metric system, force is measured in units called Newtons (N).

2. How is force measured in Newtons?

Force is measured by multiplying an object's mass (in kilograms) by its acceleration (in meters per second squared). This product is expressed in Newtons, which is equal to 1 kilogram-meter per second squared (1 kg*m/s^2).

3. How does force in Newtons differ from other units of force?

Force can be measured in different units, such as pounds or dynes, but Newtons are the standard unit in the metric system. Other units of force can be converted to Newtons by using conversion factors.

4. How is the force of gravity measured in Newtons?

The force of gravity is measured in Newtons by multiplying an object's mass by the acceleration due to gravity (9.8 m/s^2 on Earth). This product is known as an object's weight, and is expressed in Newtons.

5. What is the relationship between force and motion in Newtons?

According to Newton's Second Law of Motion, force is directly proportional to an object's acceleration. This means that the greater the force applied to an object, the greater its acceleration will be in the direction of the force. Therefore, the unit of force in Newtons is a measure of an object's ability to accelerate.
