Frictional force is the force that opposes the motion of an object when it is in contact with a surface. It is dependent on the coefficient of friction and the normal force.
Given:
Mass of the body (m) = 2 kg
Displacement (d) = 5 m
Applied force (F) = 10 N
Coefficient of friction (μ) = 0.4
To find: Frictional force (Ff)
1. Calculating the Normal Force:
The normal force (Fn) is the force exerted by a surface to support the weight of an object resting on it. It acts perpendicular to the surface.
The normal force can be calculated using the formula:
Fn = m * g
where m is the mass of the body and g is the acceleration due to gravity (approximately 9.8 m/s²).
Given: m = 2 kg
Using the formula, Fn = 2 kg * 9.8 m/s²
Fn = 19.6 N
2. Calculating the Applied Force in the Direction of Motion:
Since the applied force is in the direction of displacement, the work done can be calculated using the formula:
Work (W) = F * d
where F is the applied force and d is the displacement.
Given: F = 10 N, d = 5 m
Using the formula, W = 10 N * 5 m
W = 50 J (Joules)
3. Calculating the Work Done Against Friction:
The work done against friction is equal to the product of the frictional force and the displacement. It can be calculated using the formula:
Work (W) = Ff * d
where Ff is the frictional force and d is the displacement.
Given: d = 5 m
Using the formula, 50 J = Ff * 5 m
Ff = 50 J / 5 m
Ff = 10 N
Therefore, the frictional force acting on the body is 10N.
Given:
Mass of the body (m) = 2 kg
Displacement (d) = 5 m
Applied force (F) = 10 N
Coefficient of friction (μ) = 0.4
To find: Frictional force (Ff)
1. Calculating the Normal Force:
The normal force (Fn) is the force exerted by a surface to support the weight of an object resting on it. It acts perpendicular to the surface.
The normal force can be calculated using the formula:
Fn = m * g

Given: m = 2 kg
Using the formula, Fn = 2 kg * 9.8 m/s²
Fn = 19.6 N
2. Calculating the Applied Force in the Direction of Motion:
Since the applied force is in the direction of displacement, the work done can be calculated using the formula:
Work (W) = F * d
where F is the applied force and d is the displacement.
Given: F = 10 N, d = 5 m
Using the formula, W = 10 N * 5 m
W = 50 J (Joules)
3. Calculating the Work Done Against Friction:
The work done against friction is equal to the product of the frictional force and the displacement. It can be calculated using the formula:
Work (W) = Ff * d
where Ff is the frictional force and d is the displacement.
Given: d = 5 m
Using the formula, 50 J = Ff * 5 m
Ff = 50 J / 5 m
Ff = 10 N
Therefore, the frictional force acting on the body is 10N.
