True. The motion of an object can be measured by observing its position change over time. This can be done by using tools such as cameras, sensors, or motion detectors to track the movement of the object.
True. Motion is always observed relative to a frame of reference, which provides a fixed point against which motion is measured. This allows us to quantify and describe the motion of an object accurately.
True. Motion is always measured in relationship to a point of reference. This point of reference can be stationary or moving itself, but it is essential for determining the position, speed, and direction of an object in motion.
False. A balanced force does not accelerate an object, but an unbalanced force is required to change the motion of an object.
False. Newton's First Law of Motion states that an object at rest tends to stay at rest, and an object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an external force.
False. Friction acts to oppose the motion of an object, slowing it down. It creates resistance between surfaces in contact, converting some of the kinetic energy into heat.

False. (Electromagnetic forces stop the motion.)
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.
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
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).
False. An object is slowing down when its speed is decreasing, which means it is decelerating, not accelerating in the direction of motion.
False. Kinetic energy is related to an object's motion or speed, not its height. Potential energy is related to an object's height, while kinetic energy is related to its motion.
