Explain why an object cannot keep accelerating?
what your talking about is terminal velocity, which is when the downward force of gravity (Fg)equals the upward force of drag (Fd). This causes the net force on the object to be zero, resulting in an acceleration of zero
Newton's second law examples?
A car starting from rest, a rocket lift-off, etc.
What friction prevents an object from moving when a force is applied?
The friction produced that stops an object moving when force is applied is 'static friction'.
What force is responsible for a tennis ball moving forward after it gets hit by a tennis racket?
The ball keeps moving forward because of its momentum, which is not a force.
How much force is needed to keep a 2kg object moving?
No force is needed to keep an object moving. An object with no forces on it keeps moving at a constant speed in a straight line. If there is any force acting on it to make it slow down, then you need just enough force to cancel the first one, in order to keep it moving.
What are 5 examples of unbalanced forces?
Anything that is accelerating or decelerating because it is only balanced when something is moving at a constant speed.
What are examples of a force?
When a ball moving hits a ball that is at rest and a human pulling out a book from a desk.

What object can move with least force to move a distance of 5 meters?
There is no fundamental relationship between the distance an object moves and the force applied to it. Once an object is moving, no force is required to keep it moving, and the distance it can move without applied force is unlimited.
Is moving water considered to be a force?
Moving water exerts force. That is not the same as being a force.
Is moving water not considered to be a force?
Moving water exerts force. That is not the same as being a force.
What are some examples of externalities?
External forces are when a force is between something outside and inside the system. Air resistance, cars moving on the road, friction, and gravity are examples of external forces.
Is a balanced force moving?
A balanced force is either not moving or at a constant velocity
Does it take the same amount of force to start something as it does to keep it moving?
No. It takes a force to put something in motion, and it takes force to stop it. To keep it moving requires zero force. If there is no opposing friction force, it will continue moving forever. If you can significantly reduce the friction, a small force can keep an object moving - just enough to counteract the force of friction.No. It takes a force to put something in motion, and it takes force to stop it.

Is it true that to keep an object moving a force must be apllied?
No, it is untrue. No force is required to keep a moving object moving.
