False. Inertia is the tendency of an object to resist changes in its state of motion. It is not a form of energy; rather, it is related to an object's mass and its resistance to acceleration or deceleration.
False
False. Acceleration can either speed up or slow down an object, depending on the direction of the force applied. If the direction of the force is opposite to the direction of the object's motion, the acceleration will slow down the object.
False. Acceleration is a measure of how quickly an object's velocity is changing, which includes changes in speed, direction, or both. So, acceleration can occur even if the speed of an object remains constant but its direction changes.
False. A negative slope on a velocity vs. time graph indicates that the object is decelerating, not that it is not accelerating. Acceleration and deceleration are both forms of acceleration, but in opposite directions.

True. Air resistance is proportional to surface area, with larger surface areas creating more drag as the object moves through the air. This can result in the object experiencing greater resistance and slowing down.
False. Inertia is the tendency of an object to resist changes in its state of motion. It is not a form of energy; rather, it is related to an object's mass and its resistance to acceleration or deceleration.
False. The acceleration of an object is directly proportional to the net force acting on it, as described by Newton's second law of motion: F=ma. This means that the greater the net force applied to an object, the greater its acceleration will be.

In the absence of air resistance, all objects fall with the same acceleration due to gravity, regardless of their mass. This acceleration is approximately 9.81 m/s^2 near the surface of the Earth.
False. Terminal velocity is the constant speed that a freely falling object eventually reaches when the resistance of the medium through which it is falling prevents further acceleration. It is the maximum speed a falling object can reach due to air resistance balancing the force of gravity.
