False. Balanced forces do not cause a change in motion. When the forces acting on an object are balanced, the object will remain at rest or continue moving at a constant velocity.
When two forces acting on an object are equal in magnitude but opposite in direction, they are said to be matched forces. These matched forces result in an object's motion remaining unchanged, leading to a state of equilibrium. This principle is described by Newton's first law of motion.
False. Forces can also set stationary objects in motion.
False. Balanced forces do not change an object's direction. Balanced forces only keep an object at rest or in a uniform motion in a straight line. If an object changes direction, unbalanced forces are acting on it.
though different terminology is used. Motion is thought of in acceleration and velocity. Now, velocity is just the distance covered over an amount of time, or speed. Acceleration is the change in speed. In general terms, any object that is standing still is being acted upon by equal and opposite forces, and if one of those forces was changed, then the object would undergo acceleration. Think of a person holding a coffee cup. Gravity is working on the object to pull it down, and his or her arm is pulling equally in the opposite direction to keep it up. If the person were to let go, there wouldn't be the upward force, and the cup would accelerate towards the Earth, and its "motion" would be changed. TRUE!

False. (Electromagnetic forces stop the motion.)

False. An object is in motion if its position changes with respect to a reference point, regardless of whether its distance from the reference point is stationary. Motion includes changes in position, direction, and speed.
False. Inertia is a property of matter that describes its resistance to changes in motion, whether that motion is starting, stopping, or changing direction. All objects, whether they are at rest or in motion, have inertia.
False. Electric forces are caused by the interaction of charged particles (like electrons and protons), but friction and contact forces are primarily a result of mechanical interactions between objects.
False. In projectile motion, the object moves in a curved path under the influence of gravity. The vertical motion is accelerated due to gravity, while the horizontal motion remains constant (assuming no external forces).
