Do you need force to make an object moving in a circle?
Yes you do. You need a force that always attracts the object toward the center of the circle. It's called a "centripetal force".
What object is moving?
You need to improve your question and give more details
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
How are the forces on a moving car balanced Surely if thrust and air resistance are equal the car will be stationary.?
No, that's not the way our Universe works. I suggest do some reading on Newton's Second Law - for instance, in the Wikipedia. Briefly, you do NOT need a NET force to keep an object moving. With a net force of zero (i.e., balanced forces): * A stationary object will remain stationary * A moving object will continue moving, at constant velocity.
To start or change the motion of an object do you need unbalanced force or balanced force?
Doesn't matter Balanced Force would mean the object is traveling at a constant velocity due to Newton's First Law of Motion (Law of Inertia) Unbalenced Force would mean the object is accelerating (or decellerating) due to Newton's Second Law of Motion
What is the force that keeps an object in motion?
An object which is moving doesn't need a force to keep it moving.
Does an object need to be moving to have energy?
Nope
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.
How the acceleration of a moving object can be increased?
In order to increase the acceleration of an object, you need to increase the net force applied to the object.
How can you Photoshop a moving object into a video?
need a program like After Effect
What powers the movement of particles?
The law of inertia; Newton's First Law. An object doesn't need "power" to move continuously; If an object (such as a particle) is moving, it will continue moving without power.
How would you make an object reach equilibrium if it's not moving?
If it isn't moving, it is already in equilibrium, and you don't need to do anything more.
What is A object that stays in place and to which a moving object is compared is a?
A reference frame? Of course, a reference frame need not be a specific object, so I'm not really sure...
Do you need force to make an object moving in a circle?
Yes you do. You need a force that always attracts the object toward the center of the circle. It's called a "centripetal force".
Give five examples of acceleration?
1) To move a standing object we need to apply force and to stop a moving object we need to apply brakes. 2) Car
Does a pair of forces cause an object to accelerate?
i need to know this
Is the net force zero if the object is not moving?
Yes, but an object with net force of zero may still be moving. The net force is zero if the object is not accelerating.
