Is it true or false that balanced forces can change an object's direction?
It is false. Change of direction is acceleration, which can only be produced by unbalanced forces.
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.
True or false the motion of an object thrown at an angle is projectile motion?
True
Which of these best describes newtons third law of motion?
Newtons third law of motion states that if one object exerts a force on another object then the second object exerts a force equal strength in the opposite direction on the first object. Basically that means that if you push someone down with the strength of 2 then they will fall with the strength of 2 in the some direction but this time they will fall down. The answer is false, because if an object doesn't do anything to another object withought exerting force.
Is this true or false circular motion occurs on Earth?
false
Only the earth exerts gravitional force on all object true or false?
false
When you push downward on Earth to make a pole vault Earth exerts an equal force on the pole. true or false?
true
When you push downward on earth to make a pole vault earth exerts an equal force on the pole is this true or false statement?
true
Is the Earth exerts on the Moon a force acting at a distance?
False,since it's an air resistance and it's a contact force.
Only the earth exerts gravitional force on all object is it true or false?
False. Every object attracts every other object, through the gravitational force.
Does newtons second law state that if an unbalanced force acts on an object it will move at constant velocity?
It can accelerate or decelerate, depending on the direction of force
When you jump on the ground the Earth exerts a greater force back up on you because it is so massive.?
The force that you exert on the Earth is equal to the force that the Earth exerts on you; for every action there is an equal and opposite reaction, so says Newton. What is different is the amount of motion that results. You move, and the Earth (apparently) does not. Actually the Earth is moving all the time, in its orbit around the sun and by rotating on its axis, but it does not noticeably move because you jump on the ground. And that is indeed because it is much more massive than you are. False.

It is false. Change of direction is acceleration, which can only be produced by unbalanced forces.
The Law of Conservation of Mass states that the equation for a chemical reaction will always be unbalanced?
False
If speed of particle remains constant then it means that no unbalanced force act on it Is it true of false?
true
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.
