What are the 2 forces acting on a sinking object?
There are 3 (I am doing physics IGCSE and my paper says state the 3 forces acting on a sinking anchor), but I only know one, upthrust!
What are the 3 things that can change velocity?
There is basically only ONE thing that can make a velocity change, and that is a force acting on an object.

How is net force on an object determined?
Add the different forces together to find the net force. For example, if you have a force of -5N acting on an object and another force of 8N acting on that object, the net force is 3 N.

What is the net external force of an object?
How do you determine the net force on an object? Decide which direction is positive motion. Motion is the opposite direction is negative The forces must in a straight line!! Add all the forces in straight line acting on the object. Example To the right is positive A 5 N force pushes a 10 Kg object to the right. A 2 N force pushes the same 10 Kg object to the left. The 5 N forces is positive and the 2N force is negative Net force = +5 N - 2 N = + 3 N To determine the acceleration use Newton's 2nd law of motion F = Mass * acceleration + 3 N = 10 Kg * a a = 10 Kg ÷ + 3 N a = +3 ⅓ m/s^2 The positive sign means the object is accelerating to the right!! If the forces are not linear, you must use vectors, but the net force in any direction is still the sum of the vectors in that direction.

What best detirmines the net force when more than one force is acting on an object?
You need to get the vector sum. You can do this by resoving all forces into its 3 axis components, adding forces in like axes, and compute the new vector.

Which is an example of balanced forces acting on an object....... 1. a kangaroo jumping 2. a car turning a corner 3. a cyclist slowing down or 4. a leaf lying on the grass?
a car turning a corner
What is the minimum number of unequal vectors that give a zero resultant?
Three One is obviously out. Two is out because if two unequal forces n and p act on an object the resultant with the minimum force in magnitude is |n - p|, which will never be 0 if n =/= p. Three can be easily resolved with a quick example. Imagine an object with three concurrent forces acting on it. Two forces, n = 3 N and p = 4 N, create an angle with each other such that the resultant is 5 N. 180 degrees from the resultant, a force, r = 5 N, is acting on the object. Thus three unequal vectors on an object can result in 0.
What is the net force of an object in equilibrium?
You and I stand on opposite ends of a small car.You are in the back, pushing it forward with a force of 100 pounds. I am in the front, pushing it backward with a force of 100 pounds.I don't know what the "force" on the car is. Is it 200 pounds, 100 each from you and me ? Do we also have to add in the weight of the car ... another 2,000 pounds of gravity pushing it downward ? How about the reaction force of the pavement ... another 2,000 pounds pushing it upward ? I don't know.But I do know the net force on the car ... it's zero. The two horizontal forces on it cancel each other, because they're directed in opposite directions. Same for the vertical forces. Which is why the car doesn't accelerate in any direction ... because the net force in that direction is zero.
What if forced are not in balanced?
If the forces on an object are not balanced then it could do one of a number of things - 1. change speed (accelerate or decelerate) 2. change direction 3. change shape 4. spin if the forces on an object are balanced then it will stay in its original direction at a steady speed (this could be zero ie stationary)
