How can an object accelerate if it is moving at a constant speed?
by adding more force
How does adding and removing of force affect a moving object and an object at rest?
For an object in motion, a force applied in the direction of the movement of the object would propel it further along that direction. The force should be equal or more than the momentum of the object. If a force in applied against the moving object in a direction opposite to the movement of the object, the velocity of the moving object is hampered. How much this decrease in velocity would occur would depend on the amount of the opposing force. If a sufficiently large force in an opposing direction is applied, it can even stop the object. If the force is not along or opposite the movement of the object, the force can change the direction of the object. If the force that was causing the movement of the object is removed, the object slows down, until it finally stops. For an object at rest, a sufficient amount of force can set the object in motion.
Does weight have an impact on force?
Yes, weight, or more precisely mass*, does have an impact on force. The impact is something like this: an object moving at a constant speed will have more force than an object traveling at the same speed with less mass.So, more mass equals proportionately more force.*Mass is a direct measurement of the amount of stuff in an object. Weight is the measurement of the apparent force of gravity on an object.
What is the force you have to overcome to start an object moving called?
I have to guess either gravity or friction.If by that you mean a force that opposes the start of motion, then your force would be static friction.Static friction only occurs before an object starts moving, as opposed to kinetic friction which occurs when the objects is moving or sliding. The equation for static friction is: Ff = (coefficient of static friction) * FNInertia
Is it true that take the same amount of force to start something moving as does to keep it moving?
It requires more force to start an object than to keep it sliding because you need a strong push to slide the box and once the box starts sliding, the friction of the floor acts between the floor and the bottom surface of the box
Why do you have to exert extra force to get a heavy object moving and then have to keep applying force to keep it moving at constant velocity?
the heavier and the bigger the object the more force you need to use to keep it moving . the less weight and the smaller an object is the less force you need to use to keep it moving. it always depends on the weight of the object and the size of the object.
Why a horse has to apply more force to start a Tonga than to keep is moving?
Because of friction. Every object has 2 friction coefficient values (called Mu and with its own symbol) - one stationary, and the other while the object is moving. It always takes more force (N) to move an object from a stand-still then it does to keep the same object moving.
What are the conditions for an object to stay at rest to keep moving velocity or to move with increasing velocity?
The condition for an object to stay at rest or if moving, keep moving at a constantvelocity is that the sum of forces acting on the object be zero or that no force actson the object.For an object to increase its velocity, in other words to accelerate, there has to bea force acting on the object. The force is the one responsible for the accelerationof the object. Recall Newton's 2nd law of motion:F = m∙awhere 'F' is the force acting on the object with mass 'm', and 'a' is the acceleration the object experiences.Read more: What_are_the_conditions_for_an_object_to_stay_at_rest_to_keep_moving_at_constant_velocity_or_to_move_with_increasing_to_velocity
Why does it make more energy to stop a moving ball than the energy required to keep it moving?
The natural tendency of a moving object is to keep moving. And it doesn't really require energy to stop it; in fact, in theory, you can gain energy from it. What is required is a force.
How can a force affect moving object?
because the force pulls up the moving object and it stops When a force is applied to a body, the body gets acceleration or retardation. so the moving object may move faster or may stop. when there is no force, the moving object will move with a constant velocity.

Do multi-stage rockets require more force to keep the rocket moving?
no they do not

How does the mass of something effects its speed on a moving object?
Only indirectly. For example, with more mass, an object will have more weight, and there will be more friction if it is on the ground. Also, according to Newton's Second Law, it will require more force to speed the object up, but also to slow it down.If an object is moving, with NO force acting upon it (which is only realistic in outer space, or under some very special circumstances), it will continue moving at constant velocity, regardless of its mass.
