When external forces are acting on a body it can be in rest position?

Yes, A body can be in rest position , when external forces are acting on it. Reason: If the two external forces applied to an object are equal in magnitude and act in opposite directions, then the net force acting on an object is zero.

What is the net external force acting on a body in uniform motion?

The first law states that a body at rest will stay at rest until a net external force acts upon it and that a body in motion will remain in motion at a constant velocity until acted on by a net external force. Net external force is the sum of all of the forcing acting on an object.

When the net external force acting on a body is equal to zero?

When the net force of the body is equal to zero, it implies that the body cannot be accelerated. This follows from Newton’s second law of motion.

When body is at rest no force is acting on it?

Answer: If an object is at rest, then there are no forces acting upon the object. It would take an unbalanced force to keep an object in motion at a constant velocity.

When can a body stay at rest even though forces act on it Class 9?

When can a body stay at rest even though forces act on it Class 9? When vectore sum of all external forces is zero a body at rest will continue to be at rest .

Would it be correct to say that inertia causes a moving body to continue in motion?

Inertia of Motion Examples. Otherwise, inertia will cause his body to continue moving at the original speed until his body is acted upon by some force. When a baseball is thrown, it will continue to move forward until acted upon by gravity.

How does the net external force affect the current state of motion of an object?

Newton’s second law of motion is closely related to Newton’s first law of motion. It mathematically states the cause and effect relationship between force and changes in motion. Newton’s first law says that a net external force causes a change in motion; thus, we see that a net external force causes acceleration.

Is there an external force required to keep a body in uniform motion?

No, no external force is required to keep a body in uniform motion. Newtons First Law states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force.

When no external force acts on a body what will be its acceleration?

It is simply expressed as if the net external force on a body is zero, its acceleration is zero. Acceleration can be non-zero only if there is a net external force on the body. Mathematically, ΣF = 0 → a = 0 ΣF ≠ 0 → a ≠ 0 i.e. a body at rest tends to remain at rest and a body which is moving continues to move.

When an object is at rest a zero net force would make the object remains at rest True or false?

His First Law states that an object with a net force of zero acting on it will remain at rest, if initially at rest, or it will maintain a constant velocity. Whenever a spring is stretched, if it is to remain motionless, it must experience equal and opposite forces at either end.

When body is at rest which is true?

A body is said to be at rest if it does not change its position with respect to the reference point.

How does force of friction depend on the area of contact of two surfaces?

The force due to friction is generally independent of the contact area between the two surfaces. Note that this relationship breaks down when the surface area gets too small, since then the coefficient of friction increases because the object may begin to dig into the surface.

What happens if the net external force is zero?

If the net external force acting on the body is zero, then its acceleration is zero.

Can a body be in the rest position if Net Force Zero?

No, if the net force acting on a body be zero, then the body won’t necessarily be in the rest position. The situation of the net force equal to zero is impossible in reality. When the net force of the body is equal to zero, it implies that the body cannot be accelerated.

What happens to the net force when an object stays at rest?

If an object stays at rest, there is no net force acting upon it. False. It just means that all of the forces acting on it are equal in opposite directions. You can look at potential and kinetic energy and the inherent force that gravity exerts on every object.

Why is a ball in static equilibrium at rest?

Since these forces are equal and opposite to each other, the vector sum of these equals zero and thus, the ball is in static equilibrium i.e. rest. An object is at rest does not mean that no force is acting on it. It is the vector sum of all such forces which equals zero for an object at rest.
