If the net force on an object is zero, then velocity of the object is constant ...
it moves in a straight line at a constant speed.
If its velocity is constant, then the net force on it is zero, regardless of its mass or speed.
Accelerate. Using Newton's second law, Net Force = mass * acceleration rearranged the equation acceleration = Net Force/mass so when the force is non zero and the mass is non zero, the object will accelerate. Note: This does not mean that the object is always at rest when the force is zero, it simply means the velocity is constant (when velocity =0, the object is at rest).
Not necessarily. The net force being 0 means the object is in translational equilibrium, but the net torque can still be non-zero if there are unbalanced forces causing rotation.
As velocity is changing that means acceleration/deceleration is taking place. Hence, Force will not be equal to zero. However, the direction of force will depend on the direction of velocity of body. So, it's not possible to predict whether the force will be positive or negative. The net force can not be found as the dimensions of body like mass and change in velocity are not given in the question.
If the forces are balanced (in other words, the net force on an object is zero), then the object will not accelerate (its velocity will not change).If the forces are balanced (in other words, the net force on an object is zero), then the object will not accelerate (its velocity will not change).If the forces are balanced (in other words, the net force on an object is zero), then the object will not accelerate (its velocity will not change).If the forces are balanced (in other words, the net force on an object is zero), then the object will not accelerate (its velocity will not change).
If the object is moving in a straight line, then the net force on it is zero. If the object is not moving in a straight path, then there is some non-zero net force acting on it even if its speed is constant. We don't have enough information to describe the magnitude or direction of the force.
An additional force of 3674N in the opposite direction, making the net force 0N, would provide constant acceleration. Since a = F/m, if F = 0 then a = 0, and constant velocity is when a = 0.
Brief form of discussion: Definitely!Verbose form:Net force is required to change speed or direction of an object's motion.No net force is required to keep it moving in a straight line at a constantspeed.
In physics, net force refers to the overall force acting on an object. A feather with no net force on it maintains constant velocity.
When an object has a net force acting on it, its velocity changes. The object will accelerate in the direction of the net force if the force is in the same direction as the object's velocity, decelerate if it's in the opposite direction, or change direction if the force is perpendicular to its velocity.
a = F/m, where a is acceleration, F is net force, and m is mass in kilograms.
The final velocity of the cart can be calculated using the formula: final velocity = initial velocity + (net force/mass) * time. Assuming the initial velocity is 0 m/s, the final velocity would be: 0 + (500N / 38kg) * 4s = 52.63 m/s.
The forces are not in equilibrium and there is a resultant(net, unbalanced) force on the object.
An object at rest or moving at a constant velocity experiences a net force of zero. This can happen when the forces acting on the object are balanced, such as when the force of gravity is equal to the force pushing up from a surface.
When there is no resultant force there is no acceleration therefore the velocity will stay the same.
Not necessarily. If the net force acting on a body is zero, the body's velocity will remain constant (assuming no other forces act on it to change its velocity), but it doesn't mean the velocity will be zero. If the initial velocity is zero, then the velocity will remain zero if the net force is zero.
F=ma. F=0, a=0. The object is either moving a constant velocity or not moving at all.
