We can infer motion in situations where it’s not directly observable by observing changes in the object’s position over time, analyzing its surroundings for indicators of motion such as displacement of objects, or using instruments like sensors to detect movement indirectly through changes in variables like velocity or acceleration. Additionally, we can rely on theoretical models or mathematical calculations to predict motion based on known factors such as forces acting on the object.
A person standing on the roadside perceives the motion of the bus and its passengers relative to their own stationary position. As the bus moves past, the person observes the bus moving from one point to another, perceiving its speed and direction. Additionally, they may notice the movement of passeRead more
A person standing on the roadside perceives the motion of the bus and its passengers relative to their own stationary position. As the bus moves past, the person observes the bus moving from one point to another, perceiving its speed and direction. Additionally, they may notice the movement of passengers inside the bus relative to its interior, such as people sitting or standing as the bus accelerates, decelerates, or turns.
A force changes the direction of motion of an object by altering its velocity vector. According to Newton's first law of motion, objects in motion tend to stay in motion along a straight line unless acted upon by an external force. When a force is applied in a direction different from the object's cRead more
A force changes the direction of motion of an object by altering its velocity vector. According to Newton’s first law of motion, objects in motion tend to stay in motion along a straight line unless acted upon by an external force. When a force is applied in a direction different from the object’s current motion, it accelerates the object, causing it to change its velocity and thus its direction of motion.
We cannot directly perceive force with our senses in the same way we perceive objects or sounds. Instead, we infer the presence of force based on its effects on objects, such as changes in motion or deformation. We often observe the results of forces rather than directly sensing the forces themselveRead more

Forces can alter the shape and size of objects through compression, where inward forces decrease size; tension, where outward forces increase size; shear, causing parts to slide past each other; torque, twisting objects around an axis; and impact, resulting in sudden deformation or damage.

Forces can alter the shape and size of objects through compression, where inward forces decrease size; tension, where outward forces increase size; shear, causing parts to slide past each other; torque, twisting objects around an axis; and impact, resulting in sudden deformation or damage. These effects vary based on factors like material properties and the magnitude, direction, and duration of the applied force.
