Random Energy (2) Energy (1) Newton / Forces (2) Newton / Forces (1)

Newton / Forces (1) – 10 Points You sit in your seat. You exert a force on the seat, and the seat exerts a force on you that is _______ and ________ the force you exerted on it.

Newton / Forces (1) – 20 Points A book is at rest. What is the net force in this scenario?

Newton / Forces (1) – 30 Points A rock is dropped off a building. There are now two forces acting on it. What are they?

Newton / Forces (1) – 40 Points This rocket blasting off is a perfect example of Newton’s ___ Law of Motion because there is an action force and an equal & opposite reaction force. Identify the action force and reaction force.

Newton / Forces (1) – 50 pts In the picture above, the man is pulling on the wall with a force of ______ The wall is pulling on the man with a force of ________ The man is pulling on the elephant with a force of _______ The elephant is pulling on the man with a force of ______ The forces, in both scenarios, are _________.

Newton / Forces (2) – 10 points What is the net force is this example? Is the net force balanced or unbalanced?

Newton / Forces (2) – 20 Points Billy throws a ball in outer space. Describe what its motion would be like, and why it would be this way.

Newton / Forces (2) – 30 Points Ronda pushes a ball down a hill. The ball continues to pick up speed. The ball is _________ing, because its motion is changing.

Newton / Forces (2) – 50 pts You do not need to slow down approaching first base in baseball. Therefore this, the resistance of a change in motion, is not affected. Unlike when you need to ‘round’ third and second base.

Newton / Forces (2) – 40 pts Wei Shi is running across the gym floor. As he approached the wall, he forced himself to stop suddenly to avoid colliding into a wall. Unfortunately for Wei, there was oil on the floor where he tried to slow himself down and he continued to slide into the wall. What force was Wei unable to overcome because of the oil?

Energy (1) – 10 pts You start running. You have increased your _______ energy, the energy of motion.

Energy (1) – 20 pts You climb a ladder and stop at the top. You have increased this type of energy.

Energy (1) – 30 pts Describe how the energy is changing in this system from point A to point B.

Energy (1) – 40 pts This is the height of a wave from equilibrium.

Energy (1) – 50 pts Blue, green, violet, and indigo light waves _______ in all directions to cause the sky to be blue as they pass through the upper atmosphere due to their short wavelengths. This act is a type of ____________, not reflection or absorption.

Energy (2) – 10 pts All energy travels in ________.

Energy (2) – 20 points Sound waves need a ________, like air particles, in order to travel to your ears. Light waves do not need this.

Energy (2) – 30 points Light waves that hit a mirror will ________ back to you so you can see yourself.

Energy – 40 points Which of these monster pop-ups has the most ‘stored’ energy? What type of ‘stored’ energy does that pop-up have?

Energy (2) – 50 Points Gertrud eats a power bar. The power bar is converted into energy that her body can use. She then uses this energy to go for a run. This scenario supports what Scientific Law?

Random – 10 Points If you know the TIME it takes an object to travel, and the DISTANCE it traveled, then you can determine this about the object.

Random – 20 Points When a wave hits a medium, it can either _________, ____________, or ___________.

Random – 30 points You can figure out the force being exerted on an object by multiplying the _________ of the object and the rate of ___________.

Random – 40 Points Wonda & Cosmo fly East at 15 kilometers per hour for 2 hours. This is describing their ________.

Random – 50 Points You can jump higher in to the air on Moon than you can on Earth because the Moon has no atmosphere. TRUE OR FALSE Explain your answer.
