A bird flies at 12.5 meters/second. The wind speed is 4.5 m/s.

What is the speed of the bird when it flies with the wind?

• 12.5 m/s

• 4.5 m/s

• 17 m/s

• 8 m/s

Choose the graph that matches the following scenario:

A student walked to his locker at a constant speed, stopped for a few seconds and then continued on the same path to class but a little faster than before.

A rocket's action is to push down on the ground with the force of its powerful engines. The reaction is that the ground pushes the rocket upwards with an equal force, but opposite in direction. Which law best explains this event?

• 1st Law - The Law of Inertia

• 2nd Law - The Law of Acceleration

• 3rd Law - The Law of Action/Reaction

• The Law of Gravity

Which law of motion?

A balloon releases its air and flies across the room in the opposite direction

• 1st Law - The law of inertia

• 2nd Law - The law of acceleration

• 3rd Law - The law of action/reaction

• The law of gravity

6.8D- During a science experiment, a student dropped a metal ball from a height of 150 m. The graph shows the distance the metal ball traveled from its initial position to where it hit the ground.

What information does the graph give you about the speed of the metal ball over time?

• The ball travels at a constant speed.

• The speed of the ball increases over time.

• The speed of the ball decreases over time.

• e speed of the ball increases at first, and then decreases as time increases.

The moon has a smaller mass than Earth. How does the moon's gravity compare to Earth's gravity?

• The moon's gravity is greater than Earth because the moon has more mass.

• The moon's gravity is less than Earth because he moon has less mass.

• The moon and Earth's gravity are the same because gravity is a constant force.

• The moon does not have gravity because it is in outer space.
