If you are accelerating, there must be an unbalanced force acting on the object. The net force is what causes acceleration according to Newton's second law, F=ma. If the forces are balanced, then the object will either be at rest or moving at a constant velocity.
When an object is accelerating, the forces acting on it are unbalanced. This means that there is a net force acting on the object in the direction of its acceleration, causing a change in its velocity.
True. Acceleration is any change in velocity, including a change in direction. So when you change direction, you are indeed accelerating.
When a car is accelerating, the main forces acting on it are the driving force from the engine that propels the car forward, and the opposing forces such as friction between the tires and the road surface, air resistance, and the car's inertia that resists the change in motion.
No, on a level surface, the sum of all applied forces equals zero if the object is not accelerating. Weight is the force exerted by gravity on an object and is equal to the mass of the object multiplied by the acceleration due to gravity.
When a car is travelling at a steady speed, the driving force from the engine is equal to the total resistive forces acting against the car, such as air resistance and friction. This balance of forces allows the car to maintain a constant velocity without accelerating or decelerating.

If the penny isn't accelerating in some way, the forces are balanced. If it is, then they're unbalanced.

The object the forces are acting on will not move, or will be moving at a constant speed (e.g. not accelerating). This is called being in 'equilibrium'.
In that case, the sum of all forces must be zero.
true
If you add up all the forces acting on an object, they are balanced if they equal zero. (They cancel each other out). If the forces acting on a object are balanced, then the acceleration of that object is zero. It may still be moving, but it is not accelerating. An object that is not accelerating, (the sum of the forces acting on it is zero), is in equilibrium.
