The net force is the vector sum of all the forces acting on a body.
What else can I help you with?
When the forces acting on an object are unbalanced the net force is zero true or false?
The net force is the vector sum of all the forces acting on a body.
Is it true or false that unbalancing the forces acting on an object gives you net force?
It is true that if the forces on an object are not balanced then there will be a non-zero net force on that object.
If a net force acts on a system the system's momentum will change True Or False?
True. The net force acting on a system will cause a change in the system's momentum. This is described by Newton's second law, which states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
Is it true that an object at rest will say at rest until a net force acts upon it?
Yes, it is true.
Is it true that the combination of all forces acting on an object is the net force?
Yes
What is true in a static equilibrium if the value of total force is equal to zero?
In equilibrium, the TOTAL or not the NET force will always be zero. Because according to newton's law, if there is a net force, the object will experience acceleration.
True or false if you know an objects mass and acceleration you can determine the net force being exerted on the object?
False. You will know nothing at all about any force acting perpendicular to the direction of motion.
The overall net force acting on a leaf falling is due to the gravitational force and air resistance exerted on the leaf true or false?
True. The overall net force acting on a falling leaf is due to the gravitational force pulling it downward and the air resistance pushing against it as the leaf falls through the air.
What is true of the resulting net force when two equal forces act on the same object in opposite directions?
Net is zero. If you push to the right with 10 lbs of force, and push to the left with 10 lbs of force, they cancel each other, net movement is zero.
If you know the objects mass and acceleration you can determine the net force being exerted on the object?
True
How can you complete this sentence so it is always true the greater the net force acting on an object?
The greater the net force acting on an object, the greater the acceleration of the object will be.
What is true of Newton's first law the law of inertia?
It describes motion when net force is zero.
