Do balanced forces cause motion?
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.
If a force is exerted on an object is it possible for that object to be moving with constant velocity?
Velocity is a vector quantity in which both magnitude and direction must be taken into consideration. For an object to have constant velocity, it is necessary that both the magnitude and the direction of the velocity must be constant. Even if either magnitude or direction is variable, velocity will not remain constant. On the other hand, speed remains constant if direction is changed and magnitude is kept constant, as speed is a scalar quantity.For an object to have constant velocity, it is necessary that the object move at a constant speed and not change course. That object must move in a straight line to have a constant velocity.
Can something keep a constant velocity in a curve?
No. It can keep a constant SPEED in a curve. But if the direction changes, then that's a change of velocity, and the direction in a curve is constantly changing.
If the net force acting on an object is 0 can you conclude that the object is at rest Why or why not?
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.
If the velocity is constant does that mean that there is no impulse?
Not necessarily. Impulse Fdt=change in momentum which could be written as mdv (constant mass, velocity changing) or dmv (changing mass, constant velocity - the so-called conveyor belt problem. Imagine a hopper filled with (say) coal is feeding the coal on to a conveyor belt. The mass of the belt increases with time, so a force has to be applied to it to keep it moving at constant velocity.
Is a force needed to keep a moving spacecraft moving in a straight line?
It depends where the space craft is. If it is in deep space far away from any large mass (like a planet, star, etc) then the answer is no. If it is close to a mass then the answer is yes. An equal and opposite force is required to balance the gravitational force to keep it moving in a straight line.
What are the conditions for an object to stay at rest to keep moving at constant velocity or the move with increasing velocity?
A body is moving at constant velocity including zero at Equilibrium Condition, No change of energy or zero force. With force a body can accelerate, move with increasing velocity.
What are the condtions for an object to stay at restto keep moving at constant velocity or to move with increasing velocity?
The Condition of Equilibrium, Force equal zero, is the condition of an object at rest or moving at constant velocity. Non-Equilibrium Condition, Force is not zero, is the condition for an object to move with increasing velocity.
Do balanced forces cause motion?
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.
If you slide a hockey puck across a frictionless ice rink these must be a horizontal force on it too keep it in the motion?
F=ma constant speed would mean 'a' acceleration is zero thus force zero. The puck would be in equilibrium, and the force would be zero at constant motion. Constant motion is constant velocity including the constant zero velocity.
Is the force required to keep a rocket ship moving at a constant velocity in deep space equal to the ship's weight?
No. Without friction or air resistance, no force is required to keep an object moving at a constant velocity. Also, by the way, just thought we should mention: In deep space, the ship has no weight.
What are conditions for an object to stay at rest to keep moving at constant velocity?
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.
What are the condition for an object to stay at rest to keep moving-at constant velocity?
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.

How does exerting force keep an object moving at constant velocity?
If it wasn't for forces acting opposing to the direction of motion, an object would continue to move in a given direction at constant speed (constant velocity) indefinitely without the need of a force exerting on it.<br><br>However due to "real world" forces such as friction or air resistance, a force equal and opposite to these opposing forces needs to be applied to an object to keep it moving at constant velocity.<br><br>These are all governed by Newton's Laws of Motion.<br>
If a force is exerted on an object is it possible for that object to be moving with constant velocity?
Velocity is a vector quantity in which both magnitude and direction must be taken into consideration. For an object to have constant velocity, it is necessary that both the magnitude and the direction of the velocity must be constant.

Can something keep a constant velocity in a curve?
No. It can keep a constant SPEED in a curve. But if the direction changes, then that's a change of velocity, and the direction in a curve is constantly changing.
