You take your dog on a walk to a nearby park. On the way, yourdog takes many short side trips to chase squirrels, examine fire hydrants, and so on. When you arrive at the park, do you and yourdog have the same displacement from home? Have you and yourdog traveled the same distance? Explain
Speed is the magnitude of the velocity. When we say speed is constant, we mean that the magnitude of the velocity is constant. If the speed of a particle is constant can we say that it doesn't experience any acceleration?
A person is driving in his/her car for some errands.
• The first errand he/she drove 2 km East and 6 km North from the home.
• He/she then drives 4 km East and 2 km South.
What is the magnitude (number) of the displacement of how far the car is located from the starting point to the nearest km?
