Describe all the ways that Newton’s Laws can apply in the game of football (Remember to talk about ALL THREE LAWS).

no links please ! :(

Answers

first law: an o-lineman standing on the line of scrimmage gets tackled to the ground
second law: a wide receiver sprinting down the line to catch a hail mary pass
third law: a d-lineman and o-lineman pushing each other back and forth (for o) to keep the d-lineman away from his quarterback
When the QB puts forward force on the ball and then lets go, the ball wants to keep moving forward. The more force he puts on the ball the more inertia it will have. And the more mass the football has the more force has to be put on it. :)

Taylor created the following table to compare the three types of rocks. What correction needs to be made to the information in the table?

Examples of igneous rock are sandstone and limestone and examples of sedimentary rock are granite and basalt.

Examples of igneous rock are granite and marble and examples of metamorphic rock and basalt and gneiss.

Metamorphic rocks are made from the cooling and hardening of sediment and igneous rock is made from high heat and pressure causing chemical change.

Igneous rocks are the cooling and hardening of magma or lava and sedimentary rock is made of sediment cemented together.

Answers

Igneous rocks are the cooling and hardening of magma or lava and sedimentary rock is made of sediment cemented together.

Igneous rocks are formed by cooling and hardening of sediment. The examples of igneous rocks include granite and basalt. Metamorphic rocks are formed by the treatment of high heat and pressure. The examples of metamorphic rocks are marble and gneiss.

What are Igneous rocks?

Igneous rock or magmatic rock, is one of the three main rock types, and the other rocks being sedimentary and metamorphic rocks. Igneous rock is formed through the cooling and solidification of the magma or lava in the volcano. The magma can be derived from partial melts of existing rocks in either a planet's mantle or the crust.

Metamorphic rock are formed from other type of rocks, however they have been substantially changed from their original igneous, sedimentary, or earlier metamorphic forms. Metamorphic rocks form when the rocks are subjected to high temperature, high pressure, hot mineral-rich fluids or, more commonly, some of the combination of these factors.

Answers

Answer:

Low Potential energy and High Kinetic energy

Explanation:

Hope this helps and have a good day! Apologies if it's wrong.<3

Answer:

Low, high

Explanation:

The potential energy for the car would be low as it is on the flat bottom of the hill. Since it is still driving, it does have some kinetic energy. I'm assuming that it is currently moving at a constant velocity, so the kinetic energy would remain high (remember, the kinetic energy of an object is the energy that it possesses due to its motion).

if you dig a hole through the earth, from one hemisphere to the other, and drop a tennis ball into it, would it get stuck at the center, since thats where gravity's at, or would it pop up out the other side??

Answers

Answer:

Depending on which hemisphere it is, like western to eastern, It would most likely get stuck at the center. You would also have to put more things into thought like acceleration, velocity, and speed.

BUT since the question asked "would it pop out the other side?", I'm assuming it's talking about northern to southern hemisphere. so in that case it would pop out the other side since gravity makes things go downwards.

Answer:

We drop a tennis ball into the hole. The stone is pulled down towards the center of the earth. It falls all the way to the middle of the earth once it reaches the middle, theres no more pull of gravity. ... It would go up a ways, then (due to the pull of gravity) fall back in the other direction, back towards the center
