What else can I help you with?
The total momentum of a group of objects is conserved unless?
b. outside forces act on the objects.
What are indirect forces examples?
Indirect forces examples include gravitational forces, electromagnetic forces, and nuclear forces. These forces act over a distance without physical contact between the objects involved.
Objects move when their what is changed?
Objects move when their balance is changed.
What are ways objects can accelerate?
Objects can accelerate through forces like gravity, friction, and applied external forces. Acceleration can also occur from changes in an object's direction or speed.
What are examples of forces that require contact to have an effect?
Examples of forces that require contact to have an effect include frictional forces, normal forces, tension forces, and spring forces. These forces rely on physical contact between objects to exert their influence.

What are some examples of externalities?
External forces are when a force is between something outside and inside the system. Air resistance, cars moving on the road, friction, and gravity are examples of external forces.

Examples of forces that require contact to have an effect include frictional forces, normal forces, tension forces, and spring forces. These forces rely on physical contact between objects to exert their influence.
Why can only external forces cause objects to move?
Because of Newton's First Law of Motion.
Are there two different types of external force?
External forces can generally be classified into two categories: contact forces, which act through direct physical contact between objects (such as friction or tension), and non-contact forces, which act over a distance without physical contact (such as gravity or electromagnetic forces). Both types of forces can influence the motion or interactions of objects.
What are some examples external forces?
gravity air resistance water resistance friction
What are object that is a mass structure?
Some examples of objects that are mass structures include buildings, bridges, dams, and towers. These structures are designed to support their own weight and resist external forces such as wind and earthquakes.
The total amount of momentum of a group of objects does not change unless outside forces act on the objects?
This statement is consistent with the principle of conservation of momentum. In the absence of external forces, the total momentum of a system remains constant. This means that the sum of the momenta of all objects in the system before a collision or interaction will be equal to the sum of the momenta after, provided no external forces are involved.
What does forces in action?
Forces in action refer to the interactions between objects that cause them to move or change their motion. These forces can be contact forces, such as pushing and pulling, or non-contact forces, such as gravity and magnetism. Understanding forces is crucial in physics to explain how objects behave and respond to external influences.
