Science
A kangaroo hops 60 m to the east in 5 s. What is the
kangaroo’s average speed?
Science
A kangaroo hops 60 m to the east in 5 s.
What is the kangaroo’s average velocity?
Science
A kangaroo hops 60 m to the east in 5 s.
The kangaroo stops at a lake for a drink of
water and then starts hopping again to the
south. Each second, the kangaroo’s
velocity increases 2.5 m/s. What is the
kangaroo’s acceleration after 5 s?
Science
You know how to combine two forces that
act in one or two directions. The same
method can be used to combine several
forces acting in several directions. Look at
the diagrams, and calculate the net force in
each diagram. Predict the direction each
object will move.
Science
How is it possible to be accelerating and traveling
at a constant speed?
Acceleration can occur simply
by a change in direction.
Thus, no change in speed is
necessary for acceleration.
Science
Explain the difference between mass and weight.
Mass is the amount of matter in an
object, and its value does not change
with the object’s location. Weight
measures the gravitational force on
an object, so it can change as the
amount of gravitational force
changes.
