What unit do we measure force in?
- The standard unit for mass is kilograms (kg).
- The standard unit for acceleration is m/s 2.

What are the different units of force?
- Force (F) = m.a (from Newton's second law of motion).
- Where, 'm' is mass and 'a’ is acceleration
- The S.I.units of mass and acceleration are kilogram (Kg) and metre per second squared (m/s²) respectively.
- So, therefore the S.I.unit of force (F) = (S.I.unit of mass). ...
- S.I.unit of force (F) = (Kg). ...
- = ( Kg m/s²)
- This S.I.unit is termed as,'Newton’ (Kg m/s²).
What unit of measurement is used for force?
The unit of measurement for force is the Newton, abbreviated N. It was named after Sir Issac Newton, in honor of his work on motion and forces.

When all the forces acting on an object are balanced, the net force acting is zero?
When all the forces acting on an object are balanced, the net force acting is zero. But, if all the forces acting on a body result in an unbalanced force, then the unbalanced force can accelerate the body, which means that a net force acting on a body can either change the magnitude of its velocity or change the direction of its velocity. For example, when many forces act on a body, and the body is found to be at rest, we can conclude that the net force acting on the body is zero.
How is force expressed?
The quantity of force is expressed by the vector product of mass (m) and acceleration (a). The equation or the formula for force can mathematically be expressed in the form of:
Why does Galileo say that objects move with constant speed when there is no force acting on them?
He could note that when a sphere is rolling down an inclined plane, its speed increases because of the gravitational pull which is acting on it.

Definition
A newton is defined as 1 kg⋅m/s 2 (it is a derived unit which is defined in terms of the SI base units ). One newton is therefore the force needed to accelerate one kilogram of mass at the rate of one metre per second squared in the direction of the applied force.
Examples
At average gravity on Earth (conventionally, g = 9.806 65 m/s 2 ), a kilogram mass exerts a force of about 9.8 newtons. An average-sized apple exerts about one newton of force, which we measure as the apple's weight.
