Heeeelllllllpppp I need this right now Which type of friction acts on an object that is not moving?
O static fluid
O fluid friction
O sliding friction
O rolling friction

Answers

Answer 1
Answer:

The friction which acts on the object that is not moving is static friction, so, option A is correct.

What is friction?

Between two surfaces that are sliding or attempting to slide over one another, there is a force called friction. For instance, friction makes it challenging to push a book down the floor. Friction always moves an object in a direction that is counter to the direction that it is traveling or attempting to move.

Static friction is 0 for an object at rest on a level surface. Static friction generates an equal and opposite force that holds the book at rest if you push horizontally with a small force.

The static friction force grows to meet the force as you push harder. The book eventually moves when the maximum static friction force is reached.

Thus, the friction is static.

Inertia is ______ to mass. directly proportional inversely proportional equal to not related to

Answers

Answer;

Directly proportional

Explanation

  • Inertia is directly proportional to mass of an object. Therefore, when the force of inertia increases the mass also increases, and when it decreases the mass also decreases.
  • According to Newton's first law of motion, also known as the law of inertia; a body remains at a state of rest or constant motion and in the same direction unless acted upon by an external force.
  • Mass of a body is totally dependent on inertia of an object, such that the more inertia an object or a body has, then the more mass it has. which means inertia and mass are directly proportional. Therefore, an object with high mass has an increased tendency to resist change in its state of motion.
Directly proportional. As mass increases, inertia increases and vice versa

A force of 2.0 n exerted on an object for 0.1 seconds increases the objects velocity by 1.0 m/s you what is the mass of the object?

Answers

Answer:

The mass of the object is 0.2 kg

Explanation:

The magnitude of the applied force = 2.0 N

The duration of application of the force = 0.1 second

The increase in velocity given to the body by the force = 1.0 m/s

From the equation of motion under acceleration, we have;

v = u + a·t

Therefore;

a = (v - u)/t

Where;

v = The final velocity

u = The initial velocity

t = The time taken for the change in velocity = 0.1 s

Given that the change in velocity = 1 m/s, we have;

v - u = 1 m/s

∴ a = (v - u)/t = 1 m/s/(0.1 s) = 10 m/s²

The acceleration, a = 10 m/s²

The equation for the applied force, F is F = Mass, m × Acceleration, a

Therefore, when the applied force, F = 2.0 N, and the acceleration, a is a = 10 m/s², we have;

F = Mass, m × Acceleration, a

2.0 N = Mass of the object × 10 m/s²

∴ Mass of the object = 2.0 N/10 m/s² = 0.2 kg

The mass of the object = 0.2 kg.
