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.
Is gravity an external force?
Gravity is not considered an external force because it is a fundamental force of nature that exists everywhere in the universe. It is always present and acts on all objects with mass, pulling them towards each other.
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.
At what point on an object is the force of gravity considered to act?
The force of gravity is considered to act at the center of mass of an object.
Why is gravity considered as a passive force?
Gravity is often considered a passive force because it acts universally on all objects regardless of their properties, without the need for any external manipulation. It does not require energy input to function and is always present, exerting its force unidirectionally towards the center of mass. Unlike active forces, gravity does not rely on interactions with other objects to manifest its effects.

The force of gravity is considered to act at the center of mass of an object.
When is projectile considered a free fall?
A projectile is considered to be in free fall when the only force acting on it is gravity. This means that the object is not being propelled or pushed by any external forces, and it is only subject to the force of gravity causing it to accelerate downward.

What is when an object could gain a velocity without an external force?
Gravity
Is friction considered an external force?
Yes, friction is considered an external force because it acts on an object from outside of it, affecting its motion or resistance to motion.
Is the force of gravity on a projectile considered positive?
In physics, the force of gravity is typically considered a negative force because it acts in the opposite direction to the motion of the projectile. Gravity causes the projectile to decelerate and move downwards.
Can gravity be considered a force?
Yes, gravity can be considered a force. It is the force of attraction between two objects with mass and is responsible for phenomena like the Earth's gravitational pull on objects.
Is gravity considered a contact force because it acts on objects directly?
Gravity is action at a distance, a non contact force
Can a car can be considered an example of gravity?
Actually gravity is an energy/force that pull things
