What is the relation of the force and inertia?
The greater the inertia, the greater is the force required to produce a constant acceleration.(F=ma). But in general, acceleration is not taken constant, in this case, there is no relation between force and inertia.
What kind of motion does a constant force produce on an object of fixed mass?
Constant acceleration. Note that all orbits approximate this condition.
What force is needed to stop an object at constant speed?
Any force will do, but the larger the force, the faster will the object stop. The force, of course, has to be applied in the direction opposite to the movement.
If an object is moving at a constant speed in one direction what is needed to change its speed or direction?
An unbalanced force
Does the spring constant depend on applied force or elongation?
the relation between force (F) and elongation (x) is F = kx where k is the spring constant. The stiffer the spring, the higher the force needed to get a certain elongation; or, for a given force, the elongation will be less for a stiffer spring
What will the mass and acceleration produce if the applied force is constant?
If the applied force is constant, the acceleration will also be constant. To know the actual amount of acceleration, you divide the force by the mass.
What is the relation of the force and inertia?
The greater the inertia, the greater is the force required to produce a constant acceleration.(F=ma). But in general, acceleration is not taken constant, in this case, there is no relation between force and inertia.
When a car begins to accelerate from rest does the net force increase?
Not necessarily. A constant net force will produce a constant acceleration, that is, the car will continue going faster and faster.
What kind of motion does a constant force produce on an object of fixed mass?
Constant acceleration. Note that all orbits approximate this condition.
What is the function of the mover?
Generates most of the force needed to produce the action.
What force is needed to stop an object at constant speed?
Any force will do, but the larger the force, the faster will the object stop. The force, of course, has to be applied in the direction opposite to the movement.
The size of the force needed to produce acceleration of an object is determined by the objects what?
Mass ?
What is function of prime mover?
Generates most of the force needed to produce the action.
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.
If an object is moving at a constant speed in one direction what is needed to change its speed or direction?
An unbalanced force
Does the spring constant depend on applied force or elongation?
the relation between force (F) and elongation (x) is F = kx where k is the spring constant. The stiffer the spring, the higher the force needed to get a certain elongation; or, for a given force, the elongation will be less for a stiffer spring
Why does a car need force from its engine when moving at a constant speed?
If there be no force ie no deceleration then no need to apply any force to compensate such a deceleration. But deceleration is there due to frictional force between the tyre and the road. Hence to compensate this we have apply acceleration. So force is needed OK Physics laws State that an object in motion will remain in motion until acted upon by an outside force. The car moving at a constant speed is being acted upon by wind resistance, gravity, and friction. Therefore force is needed to retain the constant speed
