On an axis in which moving from right to left is positive, what is the displacement and distance of a student who walks 32 m to the right and then 17 m to the left? Displacement is -15 m and distance is -49 m .

21 lis 2023 · Distance in physics is understood as the speed of an object multiplied by the total time taken by the object to travel the length of its path. When calculating the distance...
4. Make distance-time graphs for different walking speeds and directions, and sketch your graphs on the axes.
Given: Use the facts that the distance d to the Moon is about 240,000 miles, and the typical person can walk at a speed, v, of about 3 miles/hour (without breaks). Concept(s): Use the concept that v = d/t → t = d/v.
Walking is energy efficient. In a walking human, one leg swings forward while the other leg’s foot stays planted on the ground. When walking at natural speed, the swinging leg uses muscle force to move forward and immediately relaxes, allowing the force of gravity to move it to the ground.
Displacement can be calculated by measuring the final distance away from a point, and then subtracting the initial distance. Displacement is key when determining velocity (which is also a vector). Velocity = displacement/time whereas speed is distance/time.
