(1) What causes an object to move, change direction, speed up or slow down? (2) Objects move when forces acting on them are Response area.
(1) What causes an object to move, change direction, speed up, or slow down? (2) Objects move when forces acting on them are unbalanced.
The sections in which the sled will experience an unbalanced force are unknown as the diagram is not provided.
(1) What causes an object to move, change direction, speed up, or slow down? (2) Objects move when forces acting on them are unbalanced.
To answer the first question, you need to analyze the diagram to identify the sections of the track where the sled experiences an unbalanced force.
Since the track is smooth and frictionless, there are no external forces acting on the sled, only the forces within the system. The only forces acting on the sled are the gravitational force pulling it downwards and the normal force exerted by the track pushing it upwards.
When the sled is on a flat section of the track, the gravitational force and the normal force are equal in magnitude and opposite in direction, resulting in a balanced force. As a result, there is no unbalanced force on the sled on flat sections of the track.
However, when the track starts to incline or decline, the normal force and gravitational force no longer cancel each other out. The component of the gravitational force parallel to the incline will cause an unbalanced force on the sled. Therefore, the sections of the track where the sled experiences an unbalanced force are the incline and decline sections.
Moving on to the second question, we need to complete the sentence:
"What causes an object to move, change direction, speed up or slow down? Objects move when forces acting on them are _______."
The blank needs to be filled with a response from the options provided. Unfortunately, the options are not visible in the text you provided. Please provide the options so that we can complete the sentence accurately.
