True or false if an object accelerates a push or pull must be acting on it?

If an object accelerates, there must be a force acting on it according to newton's second law, so I would answer true.

False. An object can accelerate without a push or pull acting on it if it is already in motion due to a previous push or pull. This is because of Newton's first law of motion, which states that an object will stay in its current state of motion unless acted on by an external force.

Is this true or false balanced forces acting on an object will change the objects velocity?
False. Balanced forces acting on an object will not change the object's velocity. When forces are balanced, there is no change in the object's velocity as there is no net force acting on the object.
When an object floats on water there is no gravity acting on it is that true or false?
False. Gravity is always acting on an object, but when an object floats on water, the buoyant force provided by the water is equal to the gravitational force acting on the object, causing it to float rather than sink.
What The weight of an object is constant true or false?
False. The weight of an object can vary depending on the gravitational force acting upon it.
When the forces acting on an object are unbalanced the net force is zero true or false?
False. When the forces acting on an object are unbalanced, the net force is not zero. This results in the object experiencing acceleration in the direction of the net force.
When the only force acting on a falling object is air resistance the object is said to be in free fall true or false?
False. When the only force acting on a falling object is air resistance, it is not considered to be in free fall. Free fall occurs when an object falls solely under the influence of gravity with no other forces acting upon it.

Balanced forces acting on an object cause the object to accelerate True or false?
false
Is this true or false balanced forces acting on an object will change the objects velocity?
False. Balanced forces acting on an object will not change the object's velocity. When forces are balanced, there is no change in the object's velocity as there is no net force acting on the object.
True or false an object in free fall accelerates until it reaches terminal velocity?
True. Got that right on a test :)
When an object floats on water there is no gravity acting on it is that true or false?
False. Gravity is always acting on an object, but when an object floats on water, the buoyant force provided by the water is equal to the gravitational force acting on the object, causing it to float rather than sink.
What The weight of an object is constant true or false?
False. The weight of an object can vary depending on the gravitational force acting upon it.
if the forces acting on an object are balanced the object may change speed change direction or do both true or false?
If the forces acting on an object are balanced, then the object will do none of those things. The statement is false.
When the only force acting on a falling object is air resistance the object is said to be in free fall. true or false?
true
When the only force acting on falling object is air resistance the object is said to be in free fall True or false?
true
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.
When the forces acting on an object are unbalanced the net force is zero true or false?
False. When the forces acting on an object are unbalanced, the net force is not zero. This results in the object experiencing acceleration in the direction of the net force.
When the only force acting on a falling object is air resistance the object is said to be in free fall true or false?
False. When the only force acting on a falling object is air resistance, it is not considered to be in free fall. Free fall occurs when an object falls solely under the influence of gravity with no other forces acting upon it.
