Can a acceleration be zero while several forces are acting on the body?
Khurrama
Yes, if all the forces vector sum to zero then there is no acceleration. For example if a you push on sled with 10 pounds and someone else pulls the other end with 10 pounds it does not move - no acceleartaion - net force is zero even though two forces are acting on it

Why is an object in equilibrium during constant motion?
When an object is in equilibrium, the acceleration is zero. When the acceleration is zero, the velocity does not change; the non changing velocity includes the case when the velocity has value zero.
If a moving body has no acceleration does it mean that no force is acting on it?
It means there is no net force acting on it. A plane in the air has no acceleration, but it does have forces acting on it. Lift pushes it up Gravity pushes it down Air resistance opposes its movement Thrust provides movement When all these forces are equal the plane will move at a constant velocity. If one of these forces becomes greater the NET force on the plane will no longer be 0 and there will be an acceleration or deceleration. Hope that helps. Another example would be space as there are no opposing forces, if in space once a speed was that speed would be constant until you 1.) decelerated with a force in the opposite direction 2.) accelerated the speed past your current velocity in your current direction 3.) Get caught by some planets gravity and crash to you death (but then this question is the least of your problems)
How does net force affect acceleration?
If net force acting on a mass decreases, the acceleration of the object decreases. But if the mass of an object were to decrease while a constant net force acted on it, its acceleration would INcrease. If the net force on the object AND the object's mass both decrease, the object's acceleration could either increase OR decrease. We'd need the actual numbers in order to calculate how it would turn out.
A juggler throws a bowling pin into the air with an initial velocity Vi another juggler drops a pin at the same instant compare the accelerations of the two pins while they are in the air?
Since the question is asking you to compare the acceleration after the pins have been released, the only force acting on each pin is gravity. Therefore, the acceleration on both pins is the acceleration due to gravity, or 9.8 m/s2 towards the earth. Even though one of the pins is being thrown up, once released, the acceleration is still 9.8 m/s2 towards the earth.Each pin has the same acceleration.
What would the acceleration of the object be the mass was triple while keeping the force the same?
The acceleration would also be trippled when the force is tippled. the relevant equation is: F=ma, where F= force m=mass a=acceleration
What are the different forces acting on the ball while it’s in the air?
Gravity, force, and acceleration.
What are the forces acting on an object without acceleration?
The net force that is acting on an object that is not changing speed is centripetal force that is pulling the object into a circular path. However, just to be clear on this point, while the object's "speed" is not changing, it's "velocity" certainly is, because velocity, unlike speed, has a directional component to it.
Is a car balanced or unbalanced when turninng while moving at a constant speed?
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.
What happens to an object's acceleration as the size of the force acting on the object increases?
F=m.a , a=F/m; acceleration is directly proportional with force. acceleration increase while force increase.
How do balanced and unbalanced forces work when you sit down?
While you're moving, the forces acting on you are unbalanced, and add up to something. When you're sitting, the forces acting on you are balanced, and add up to zero.
What does an unbalanced force mean?
It means that the total force, when added as a vector, is not zero. Unbalanced forces will cause a mass to accelerate, while a balanced force will keep it at rest (or in motion at constant velocity) without acceleration.
What forces are acting on the International Space Station while its in orbit?
Gravity and atmospheric drag.
What are the forces act on a skateboard?
There are several forces involved while riding a skateboard. The force of friction (air resistance and contact with ground) acting against the motion and the pushing force from when you push off with your foot acting with motion. There are also several normal reaction forces, the weight of the person on the skateboard and the weight of the skateboard on the ground.
As long as an object at rest is there a force acting against it?
There can be forces acting on an object while it is at rest, as long as the forces cancel each out. For example: a block laying on a table feels the force of gravity pulling it down, but the table pushes up with the same force. Therefore, the forces cancel and the object remains at rest.
What is the Difference between like and unlike parallel forces?
Forces which are parallel and acting in same direction are called like parallel forces. Forces which are parallel and acting in opposite direction are called unlike parallel forces.
Why is an object in equilibrium during constant motion?
When an object is in equilibrium, the acceleration is zero. When the acceleration is zero, the velocity does not change; the non changing velocity includes the case when the velocity has value zero.
Is there a difference between positive and negative g-force?
Yes, positive g-forces push objects in the direction of acceleration, while negative g-forces push objects in the opposite direction of acceleration. Positive g-forces can be felt as a sensation of weight, while negative g-forces can feel like weightlessness or the sensation of falling.
