An asteroid traveling through space at a constant speed is experiencing balanced forces. In this case, the net force acting on the asteroid is zero, meaning that any forces acting on it (such as gravitational pulls from nearby celestial bodies) are equal and opposite, resulting in no change in its motion. Thus, the asteroid maintains its constant speed without acceleration.
Must be unbalanced. Otherwise, the moon would be moving at constant speed in a straight line.
Inertia is the "force" that causes an object in a curved path to pull away from the center. Inertia is actually the tendency of anything with mass to resist a change in motion. In other words, an object at rest will not move because of inertia, unless it is acted on by an unbalanced force, and an object in motion will continue to travel at a constant speed in a straight line unless acted on by an unbalanced force. An object traveling in a circular path pulls away from the center because inertia tries to keep the object traveling in a straight line.
There is only one force acting on an orbiting spacecraft ... the force of gravity.It's NOT correct to say that a constant speed in a curved path indicates balanced forces.That's true only when the constant speed is in a straight line. If the direction is changing,there must be net forces on the moving object, even if its speed is constant.
On the Moon: The weight of a 53 kg astronaut on the Moon would be approximately 212 N, based on the acceleration due to gravity on the Moon (1.6 m/s^2). On Mars: The weight of a 53 kg astronaut on Mars would be approximately 199 N, based on the acceleration due to gravity on Mars (3.7 m/s^2). In outer space traveling at a constant velocity: In the absence of gravity in outer space, the astronaut would experience weightlessness and have no weight, even while traveling at a constant velocity.
Kepler's third law states that the square of an asteroid's orbital period is directly proportional to the cube of its average distance from the sun. This means that as the distance from the sun increases, the orbital period of the asteroid also increases.
The forces on a car traveling at a steady speed are balanced. The driving force from the engine is balanced by the resistive forces such as friction and air resistance. This balance allows the car to maintain a constant speed.
A balanced force will not cause a moving object to change its constant speed. It's an unbalanced force that would either speed up or slow down the moving object.
No. An unbalanced force causes motion, but balanced forces keep a body in motion in a straight line at constant velocity, or at rest at constant 0 velocity.
When forces are balanced, the object remains at rest or continues to move at a constant velocity. When forces are unbalanced, there is a net force acting on the object, causing it to accelerate in the direction of the greater force.
An object with balanced forces acting on it is still. An object with unbalanced forces acting on them moves at an non constant velocity. It is possible for an object to have balanced forces acting on it and yet move in a vacuum.

There is no such thing as "a balanced force" or "a unbalanced force". Only a group of two or more forces can be balanced or unbalanced. An unbalanced group of forces acting on an object causes accelerated motion of the object. A balanced group of forces doesn't.
* Balanced: The vector sum of all forces on an object is zero. The object does not accelerate.* Unbalanced: The vector sum of all forces on an object is NOT zero, the object DOES accelerate.
Balanced forces on an object result in no change in its motion, as the forces cancel each other out. Unbalanced forces cause an object to accelerate in the direction of the net force applied. For a stationary object, balanced forces maintain its position, while unbalanced forces cause it to start moving. An object moving at a constant velocity experiences balanced forces, while unbalanced forces can change its speed or direction.
When a lorry is traveling at a constant speed, the driving force from the engine is balanced by the resisting forces such as air resistance, friction between the tires and the road, and other resistance forces. This balance of forces allows the lorry to maintain its constant speed.
Balanced forces are used to keep an object at rest or moving at a constant velocity, while unbalanced forces are used to accelerate or decelerate an object. Both types of forces are necessary to understand the motion of objects and how they interact with their environment.
The forces acting on the car are unbalanced because it is accelerating by changing direction, even though it has constant speed. Unbalanced forces cause acceleration (change in motion). That is what Newton's first law of motion is about.
