When does friction happen, and what is a product of it?

When two objects touch or rub together, causing one of the objects to slow down. Friction produces heat.

EX: A ball rolling over the grass.

Stepping onto a dock from a boat, and the boat pushes backwards as you step forward?

Law 3:

For every action there is an equal and opposite reaction

An energy pyramid offers a visual understanding of how organisms interact within a food chain. The level of the pyramid with the most available energy is always the producer, which is located where?


What percent is passed from one organism's level to another?

On the bottom of the pyramid


10%

193 N represents what?

Force

100

This subatomic particle, which carries a negative charge, is the only one that actually moves during static discharge.

Electron

200

What is intertia?

An object's ability to resist changing what it is already doing.

200

Taking more force to move or accelerate an item like a basketball, then a ping pong ball.

Law 2:

Force = Mass x Acceleration

200

What is gravity known to do?

Bring something back down toward Earth

200

46 m/s represents what?

Speed

200

This fundamental law of electrostatics states that a positive charge and a negative charge will do this to one another.

Attract

300

This scalar quantity is defined simply as the distance traveled divided by the time it took to get there.

Speed

300

While playing kickball, players look onward as the ball gets kicked over their heads and rolls toward the back of the field. It only stops because it runs into the fence.

Law 1:

An object in motion tends to stay in motion, and an object at rest tends to stay at rest unless acted on by an outside force.

A little girl is sitting on top of her desk. What forces are keeping the girl in place?

The girl is pushing down on her desk, while her desk is pushing up on the girl with an equal amount of force.

134 kg represents what?

Mass

300

Regardless of size, every magnet has exactly two of these, labeled North and South.

Poles

400

Unlike speed, this quantity is a vector, meaning it includes both a numerical value and a specific direction.

Speed + Direction

Velocity

400

Jumping up and down really quickly on a pogo stick gives you a headache when you go inside.

Law 1

400

If I am trying to push a heavy box with friends, and we push it 25 N to the right, 30 N to the left, and 60 N to the right, what is the net force strength and direction of the box?

55 N to the right

400

950 km/hr East represents what?

Velocity

400

This giant spark of static electricity occurs when a massive buildup of charge in a cloud discharges to the ground.

Lightning 

500

If the line on the distance-time graph is curving upward (getting steeper), the object is undergoing this process.

Accelerating

500

How is a balloon being filled with air and released out, an example of newton's third law of motion?

The balloon is filled with air, and the air is released causing the air to come out of the balloon while also flying around in the air. This is an example of newton's 3rd law: equal and opposite reaction

500

What is the formula to calculate force?

F=ma

500

12 m/s squared represents what?

Acceleration
