Since the system is accelerating.coconut62 said:Please refer to the image attached.
How come the answer is 0.42N?
No. Inertia is the fact that it requires a net force to accelerate a mass. Quantitatively, it's the force divided by the acceleration.coconut62 said:I want to ask, is this related to inertia? Is inertia partly because of air resistance/frictions?
coconut62 said:So actually does inertia cause an object to require more force to stop/start moving?
For example, if I were to push an object of 10kg across a frictionless table, the force required for the object to start moving is due to its big mass only, or does it include inertia?
Friction is a force that resists motion between two surfaces that are in contact with each other.
Friction can cause tension on a horizontal rough surface to increase, as it acts in the opposite direction of the applied force, making it harder for the object to move.
The amount of friction on a horizontal rough surface is affected by the roughness of the surface, the weight and surface area of the object, and the type of material the surfaces are made of.
The tension on a horizontal rough surface can be calculated by using the equation T = μN, where T is the tension, μ is the coefficient of friction, and N is the normal force.
Friction on a horizontal rough surface can be reduced by using lubricants, smoothing out the surface, or using materials with lower coefficients of friction.
