You and your dog are playing tug-of-war. For a while, neither of you are winning, but after a few hard tugs you are able to pull the toy away from your dog. What happened in this scenario?
The forces were unbalanced when no one was winning and then balanced when you pulled the toy away.
The forces were balanced when no one was winning and then unbalanced when you pulled the toy away.
There were no forces acting on the toy when it was a tie, then were balanced when you pulled the toy away.
There were no forces acting on the toy when it was a tie, then were unbalanced when you pulled the toy away.

The forces acting on the cart are (a) , causing the cart to move to the (b) _
The forces acting on the car are (a) . The direction of the movement of the car will be (b) .
The forces acting on the cart are (a) , causing the cart to (b) __
The forces acting on the cart are (a) , causing the cart to move to the (b) __
The forces acting on the cart are (a) , causing the cart to move to the (b) _
(a) cause the motion of an object to change, while (b) do not cause a change in motion.
When forces acting on an object are equal, they are considered (a) . This means the object has (b) and the object has (c) or constant motion.
When the forces acting on an object are not equal, the forces are considered to be (d) . This means the object has (e) in a specific direction with a specific amount of net force.
What is a balanced force
Study of accelerating objects and the forces that acting upon those objects
Study of objects that are at rest or at constant velocity
Forces that are opposite in direction and equal in magnitude
Forces that are in the same direction or not equal magnitude
Which one is balanced?
top
bottom
both
Neither is balanced
A book rests on a table. The force of gravity pulls down on the book with a force of 20 newtons. What prevents the books from moving downward?
The table presses back up on the book with an equal and opposite force of 20 newtons.
The table presses back up on the book with a force greater than 20 newtons.
The table and the book together are accelerating downwards at 9.8 m/sec2
The inertia of the book holds it up
