when the mass is increased, the force will also increase just a small hint
When the mass of the counterweight increases, the force required to lift it also increases. This is due to Newton's second law of motion, which states that the force exerted on an object is directly proportional to its mass and acceleration. Therefore, as the mass of the counterweight increases, the force needed to overcome its weight and lift it also increases.
To understand how the force required to lift the counterweight changes when its mass increases, let's consider Newton's second law of motion: F = m * a.
In this equation:
- F represents the force applied to an object,
- m represents the mass of the object, and
- a represents the acceleration of the object.
When an object of mass m is lifted, the force required to lift it is equal to its weight. The weight of an object is given by the equation: W = m * g.
In this equation:
- W represents the weight of the object,
- m represents the mass of the object, and
- g represents the acceleration due to gravity (approximately 9.8 m/s² on Earth).
Since the force required to lift the counterweight is equal to its weight (W), we can conclude that F = m * g.
Now, if the mass of the counterweight increases by adding more mass, the force required to lift it will also increase. This is because the weight of the counterweight (and hence the force required to lift it) is directly proportional to its mass.
