student drops a feather and rock at the same time from Mrs. Taylor’s window. If air resistance wasn’t a factor, what should she observe?
What is, the rock hits the ground first due to more mass.

What is the Net force of the image below?
What is 400N Down/South

What is the main difference between weight and mass?
Weight is affected by gravity, while mass is not. Mass is just how much matter you are made up of

According to Newton’s laws, for any object, the greater the force that's applied to it, the greater its ____ will be.
What is acceleration?

If you apply the same force to a bowling ball, and a tennis ball, which will move farther and why?
What is the tennis ball will move farther due to it having less mass, thus requiring less force to move it a further distance.

A group of students is playing tug-of-war. The students on both sides of the rope are pulling with equal force so that the rope is not moving. This is an example of
What is a balanced force (no motion)

Why does someone not wearing a seatbelt in a car fly forward when the car stops suddenly? Make sure to include which law explains this.
What is the body wants to keep moving forward because of inertia. Objects want to keep moving the way they were moving, so the body flies forward. This is Newton's 1st Law

Name the 3 types of friction and describe each one.
Static Friction- Between objects not moving
Sliding Friction: Between objects sliding past one another
Rolling Friction: Between rolling object and the ground.

Why does it take more effort to make a bowling ball accelerate 25 m/s2 than to make a tennis ball accelerate 25 m/s2 ? Make sure to include which law explains this.
Answers may vary. As long as the answer talks about how the objects have differing masses, thus require different amounts of force to move them farther

Explain the difference between balanced and unbalanced forces, and how they affect the motion of an object. Include what the net force always is for balanced forces. You may sketch a picture to support your answer, if that helps.
Balanced forces=no motion, Unbalanced forces cause motion. Net force for balanced forces is always 0N since there is no motion.

An astronaut is planning a trip to a newly-discovered planet. According to the Law of Universal Gravitation, the astronaut's weight on the new planet will be greater than his weight on Earth if......
What is, if the planet has more gravity than Earth
