How can you tell visually if the forces on an object are balanced?
If the object is not moving, or is traveling at a constant velocity, all forces acting on the object are equal and opposite to each other. If the object is accelerating (speeding up, slowing down, or changing direction) the forces are not balanced.
How can you tell if the force on an object are balanced?
If the object is not moving, or is traveling at a constant velocity, all forces acting on the object are equal and opposite to each other. If the object is accelerating (speeding up, slowing down, or changing direction) the forces are not balanced.
How can you tell if a force is balanced or unbalanced by looking at it?
2 Forces are unbalanced when an object that is not moving starts moving or changes speed or direction. Balanced forces are the opposite they are where an object that is not moving stays still or an object that is moving stays at a constant pace.
If the forces on an object is balanced what does it tell you about the size and direction of the force?
If the forces on an object are balanced, it means that the size and direction of the forces are equal and opposite. This results in no acceleration of the object, and it remains in a state of equilibrium.
What can the changes in a objects position tell you about the forces acting on the object?
Since any object's acceleration is proportional to the net force on the object, the object's motion will tell you about the net force on it, i.e., the vector sum of all forces acting on the object. However, you will not be able to tell anything about the individual forces unless there is only one.
Can you say about the no forces acting on a stationary object?
If the object is not moving, then the only thing you can be sure of is that since it's not accelerating, all of the forces acting on it add up to zero. Just the fact that it's not moving is not enough information to tell you that there are no forces on it.
When an item is traveling at a constant speed what must be true about the forces acting on that object?
You can't tell anything about them from the speed alone. Constant speed aloneisn't enough to tell that there are no forces on the object. The best example isa planet in a circular orbit around the sun. Its speed is constant, even thoughthere's a substantial gravitational force between it and the sun.When an item is traveling at a constant speed and also in a straight line, thenthe forces acting on it must either be nonexistent or must add up to zero.
How do unbalanced forces affect an object's speed?
Newton's Laws of Motion tell us that the velocity of a body remains constant unless subject to a force. If there are more than one force acting, it will be the net force that causes any change in velocity. So in the case where the forces are balanced, nothing will change, but note you must be sure the forces are balanced in direction as well as magnitude. In fact what you have to do is evaluate the net force as a vector quantity. If the forces are in fact unbalanced this means there is a net force in a certain direction, and this will act on the body, in that direction. (Force = mass x acceleration)
What will knowing the net force on an object tell about the forces on the object?
Knowing the net for will tell you various things, including the direction, speed, and acceleration.
How can can you tell if opposite forces are balanced or unbalanced?
Opposite forces are balanced when they are equal in magnitude and opposite in direction, resulting in no change in an object's motion. They are unbalanced when one force is greater than the other, causing the object to accelerate or change its motion. The net force acting on an object is calculated by subtracting the smaller force from the larger force and considering the direction.
What does an object floating tell you?
An object floating typically indicates that it has a density lower than the fluid it is in. This buoyant force counteracts the force of gravity, allowing the object to stay suspended on the surface. Objects float due to a balance of these two forces acting upon them.
Why does the shape of the free fall curve tell you about how an object moces when it is in free fall?
if its a velocity / time curve, it will show diminishing acceleration (slope of the curve) up to terminal velocity (forces balanced)
