Certainly not. An object has momentum on account of its motion, which depends on
its mass and its velocity. Force may be involved in the object's motion, but doesn't
need to be.
If we let the discussion become somewhat flabby, we can imagine a constant force
applied to an object, and asked what happens to the object's momentum.
An object with a constant force acting on it exhibits constant acceleration in
the direction of the force. In that situation, the object's speed, and therefore
its momentum, are proportional to the time the force continues to act on it.
An object moves with constant velocity when there is no net force acting upon it. If there are no forces acting on an object, or if the forces acting on it "cancel out" leaving a net force of zero acting on the object, it will have zero acceleration. With a zero acceleration, the velocity of the object will be constant.
Yes, an object can have a constant speed but varying velocity if it changes direction while moving at that speed. Velocity includes both speed and direction, so if an object is moving in a straight line at a constant speed but changing direction, then its velocity is constantly changing even though its speed remains the same.
consider a sphere moving through a viscous medium the fluid layer in contact with the sphere is moving with same velocity but the layer far away is at rest. This makes a relative motion to be setup.viscous force acts on this drop.The backward force is proportional to the speed of the drop.at a stage the viscous force balances the downward force.hence the body moves with a constant velocity called terminal velocity.
If an object has no net force acting on it, it will either remain at rest or continue moving at a constant velocity in a straight line, following Newton's first law of motion.
Speed is equal to the magnitude of velocity when the object is moving in a straight line without changing direction. In other words, if the velocity vector is pointing in the same direction as the motion of the object, then the speed will be equal to the magnitude of the velocity.
Constant speed, moving in a straight line, zero acceleration, zero net force acting on it.
An object moves with constant velocity when there is no net force acting upon it. If there are no forces acting on an object, or if the forces acting on it "cancel out" leaving a net force of zero acting on the object, it will have zero acceleration. With a zero acceleration, the velocity of the object will be constant.
When a body moves with constant velocity, the net force acting on it is zero as there is no acceleration. The magnitude of the force applied to keep the body moving is equal to the frictional force opposing its motion. This ensures that the forces are balanced, resulting in a constant velocity without any acceleration.
The condition for equilibrium is when the net force acting on an object is zero and the object is either at rest or moving at a constant velocity. This means that the forces acting in opposite directions are equal in magnitude and balanced.
If the crate is moving at a constant velocity, then the force of friction acting on the crate is equal in magnitude and opposite in direction to the force you are applying to push the crate. This means that the force you apply to push the crate is balancing out the force of friction acting against it. By measuring the force you are exerting and observing the constant velocity of the crate, you can infer the magnitude of the friction force.
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.
In order for an object to travel with constant velocity the sum of forces acting on it must be zero
When an object is moving at a constant velocity, the forces acting on it are balanced. This means that the net force on the object is zero, which allows it to continue moving at a constant speed in a straight line. The forces acting on the object may include friction, air resistance, and any applied forces.
No,because if the car is moving at a constant velocity that means the acceleration is zero. So the net force is zero and there may be some forces acting on it. Only gravity, downward.
The condition for an object to stay at rest or if moving, moving at a constant velocity is that the sum of forces acting on the object be zero or that no force acts on the object.
If the crate is moving at a constant velocity, the friction force is equal in magnitude but opposite in direction to the pushing force, so it is also 100 N. This is because the two forces are balanced and there is no net force acting on the crate.
If an object is at rest or moving at a constant velocity, the forces acting on it are considered to be balanced. This is because in such cases, the net force acting on the object is zero, meaning that the forces are equal in magnitude and opposite in direction.
