How can one determine the friction force when given the mass and acceleration of an object?
To determine the friction force when given the mass and acceleration of an object, you can use the formula: friction force mass x acceleration. This formula helps calculate the force resisting the motion of the object due to friction.
How is the equation fn mg ma used to calculate the force of friction acting on an object of mass m moving with acceleration a?
The equation fn mg ma is used to calculate the force of friction acting on an object of mass m moving with acceleration a by subtracting the force of gravity (mg) from the force needed to accelerate the object (ma). The remaining force is the force of friction.
What is the relation between friction force and acceleration?
The friction force acting on an object is directly proportional to the object's acceleration. As acceleration increases, the friction force opposing the motion of the object also increases. This relationship is described by the equation F_friction = μ * N, where μ is the coefficient of friction and N is the normal force acting on the object.
Which formula is used to calculate the mass of an object if the force and acceleration are known?
The formula used to calculate the mass of an object when force and acceleration are known is given by Newton's second law of motion: mass = force / acceleration. This formula states that the mass of an object is equal to the force acting on it divided by the acceleration produced.
How can I calculate the g force experienced by an object from its acceleration?
To calculate the g force experienced by an object from its acceleration, you can use the formula: g force acceleration / 9.81 m/s2. This formula helps you convert the acceleration of the object into the equivalent force of gravity, measured in multiples of g (9.81 m/s2).

How does friction affect the net force on an object?
Friction acts in the opposite direction to the motion of an object, so it reduces the net force acting on the object. This reduction in net force can impact the acceleration or deceleration of the object. The net force is the sum of all forces acting on an object, including friction.
What term describes the result when force is apllied to an object?
The object is given an acceleration if the force exceeds the force of static friction on the object.

The more of what object has the more force it takes to move it?
You increase the object's acceleration.
Can friction or acceleration due to gravity affect the weight of an object?
Friction and acceleration due to gravity do not directly affect the weight of an object. Weight is determined by the gravitational force acting on the object, which is independent of these factors. However, friction can affect the apparent weight of an object on a surface by opposing the force of gravity.
How does friction affect movement of object?
Friction provides a force, and therefore an acceleration, in the opposite direction of motion.
How can one determine the coefficient of friction in a given scenario?
To determine the coefficient of friction in a given scenario, one can calculate it by dividing the force of friction by the normal force acting on an object. The force of friction can be measured using a spring scale or force sensor, while the normal force can be calculated by multiplying the mass of the object by the acceleration due to gravity. The coefficient of friction is a dimensionless value that represents the amount of friction between two surfaces.
How do you calculate friction?
A rightward force of 25 N is applied to a 4-kg object to move it across a rough surface with a rightward acceleration of 2.5 m/s/s. Use the diagram to determine the gravitational force, normal force, frictional force, net force, and the coefficient of friction between the object and the surface
