What two things must you know to describe the motion of an object?
Distance is
What is the displacement of a cyclist, who travels 1 mile north, then 1 mile east, and finally 1 mile south?
Define speed
How do speed and velocity differ?
How do velocities combine? In opposite directions? In the same direction?
A river flows at a velocity of 3 km/h relative to the riverbank. A boat moves upstream at a velocity of 15 km/h relative to the river. What is the velocity of the boat relative to the riverbank?
The rate at which velocity changes is called
True or false? Acceleration is the result of increases or decreases in speed.
A horse on a carousel that is moving at a constant speed is accelerating because
True or false? When the final velocity is less than the initial velocity of an object, the acceleration is negative.
The total distance traveled divided by the total time is
What are some common units for speed (give at least two)
Define velocity
Define acceleration
A quantity that has both magnitude and direction is called a .
