What happens when An object stays a rest until what acts upon it?
An object will remain at rest until an external force is applied to it. This force could initiate motion in the object or change its state of rest.
What happens to the pen what could have coused the pens motion?
The pen was pushed by an external force, such as someone's hand or another object, which caused it to move. When a force is applied to an object, it can cause the object to accelerate and change its position.
What happens to an object when it experiences a nonzero external force?
When an object experiences a nonzero external force, it accelerates in the direction of the force according to Newton's second law of motion (F=ma). The object's velocity changes, causing it to either speed up, slow down, or change direction depending on the direction of the force.
What happens to an object when there is no force acting on it?
If there is no external force acting on an object, it will continue to move at a constant velocity or remain at rest, according to Newton's first law of motion. This is also known as the law of inertia.
What happens when an object in a vacuum has no external forces acting upon it?
When an object in a vacuum has no external forces acting upon it, it will continue to move at a constant velocity in a straight line due to the absence of any opposing forces like friction or air resistance. This is known as Newton's first law of motion.
What is the net external force formula used to calculate the overall force acting on an object?
The net external force formula is: Fnet ma, where Fnet is the net external force, m is the mass of the object, and a is the acceleration of the object.
What is the direction of force acting on an object when it is subjected to external influences?
When an object is subjected to external influences, the direction of the force acting on the object depends on the nature of the external influences. The force can be in any direction, depending on the specific circumstances of the situation.
What happens to the mass of an object what happens to the acceleration?
If the mass of an object increases, what happens to the acceleration?
Why is weight an external force?
Weight is considered an external force because it is the force exerted by gravity on an object due to its mass. Gravity is an external force acting on the object from the outside environment.
What happens to particles when an object expands and contracts?
When an object expands, the particles within the object move farther apart from each other, increasing the object's volume. When the object contracts, the particles move closer together, decreasing its volume. This expansion and contraction occur due to changes in temperature, pressure, or other external factors.
What is the effect of external forces on the center of mass of an object?
External forces can cause the center of mass of an object to accelerate or change its position. The direction and magnitude of the external forces determine how the center of mass moves.
Is weight a external force or an internal force?
Weight is considered an external force because it is the force exerted by gravity on an object due to its mass. It is not generated by the object itself, but rather acts on the object from the outside.
