Motion and Forces

Question 1

What is Motion?

Answer 1

Motion is described as a change in location of an object.

Question 2

When does motion occur?

Answer 2

Motion occurs when an object changes position relative to a reference point.

Question 3

Give an example of Motion.

Answer 3

When a car goes by, it is changing location. And we are the. We are the reference point.

Question 4

What is Distance?

Answer 4

Distance is how far an object has traveled.

Question 5

What is Displacement?

Answer 5

Displacement refers to the change in position from the starting point.

Question 6

Give an example of Distance.

Answer 6

For example if your grandmother lives 15 miles away in order to visit, you have to cover 15 miles of distance.

Question 7

Give an example of Displacement.

Answer 7

Visiting 15 miles from your grandmother is also the displacement. When you come back, you have no displacement. The displacement will always be 0 but your distance will be double the original distance. ( 15 there and 15 back= 30miles 15*2= 30) (if you go 15 there and 15 back, displacement is 0)

Question 8

What is speed?

Answer 8

(“I am speeeeeed” Speed is how fast you cover distance.

Question 9

Give an example of Speeeeeeed.

Answer 9

If you cover 30 miles. It is 30 mph miles per hour. Distance divided by time is the formula for the speed!!

Question 10

What is Velocity.

Answer 10

Velocity includes the direction of motion.

Question 11

Give an example of Velocity.

Answer 11

If you are in a car crash. If you’re a passenger in a car and the person driving runs into the person in front that is going the same direction. They may be going the speeds but that is called a fender bender. There might be an accident but it is not going to be big. But if you have 2 cars going the opposite directions driving right towards each other going the same speed is a much bigger deal. Direction changes the quality of a motion.

Question 12

What is Acceleration?

Answer 12

Acceleration is when you change the velocity. Slowing down is called deceleration. It is a form of acceleration. Acceleration is if you’re going one velocity, then you speed up or slow down, you’re experiencing acceleration and deceleration.

Question 13

Give an example of Acceleration.

Answer 13

Any time your speed changes, if 0 to some motion. If you go 60 to 70 mph or 60 to 50, it is a change in velocity.

Question 14

If you are traveling straight away and you double back, throw and reverse, without any sort of change, it is ___________ because you change some quality.You changed the ___________.

Answer 14

Acceleration and Direction

Question 15

What is force?

Answer 15

Force is any push or pull

Question 16

Give an example of a force.

Answer 16

If you and your buddy pull the same amount for tug of war, the net force is 0. If someone helps your buddy. It is going to move in their favor, and not yours.

Question 17

What is friction?

Answer 17

Friction is any interaction between surfaces with two active objects. It can be more solid and liquid. It can be only 1 solid.

Question 18

What is an example of friction.

Answer 18

Fluid friction is going to be any time the surface of an object interacts with its environment air currents or water or fruit and jello. It is experiencing fluid friction.

Question 19

What is rolling friction?

Answer 19

Rolling friction is less motion and effort.

Question 20

Give an example of rolling friction.

Answer 20

For example, a bike is easier to ride than walking or running because the rolling reduces the amount of work necessary to move along.

Question 21

What is Newton’s 1st Law?

Answer 21

1st Newton’s law. (Inertia) An object in motion wants to stay in motion and an object in rest wants to stay at rest.

Question 22

Give an example of Newton’s 1st law.

Answer 22

If you go on a super long vacation and you sleep in all day, and do nothing active, the first few days are a nightmare. You have settled in on the lack of productivity and movement.

Question 23

What is Newton’s 2nd Law?

Answer 23

Newton’s 2nd law. Less mass takes up less force. More mass takes up more force

Question 24

Give an example of Newton’s 2nd Law

Answer 24

If you kick a soccer ball, it has no give. But if uou kick a solid tungsten, it would be hard because of the mass. It takes more force because of the mass. Less mass takes up less force.

Question 25

What is Newton’s 3rd Law?

Answer 25

Newton’s 3rd law. For every action or force there is an equal and opposite reaction or force.

Question 26

Give an example of Newton’s 3rd Law

Answer 26

If you throw a water bottle at the ground, the ground is hitting the water bottle back with the same amount of force as the water bottle is hitting the ground. ( spaceship)

Question 27

What is gravity?

Answer 27

Gravity is the universal attractive force between objects.

Question 28

What The Centripetal Force?

Answer 28

Centripetal force is It is going to be a change in velocity that is drawn towards a circular path.

Question 29

Give an example of Gravity.

Answer 29

You are attracted to whatever is physically closest to us right now.

Question 30

Give an example of the Centripetal.

Answer 30

If you keep tilting a plate, you will get the marble to go around it like a perimeter.
