Newtons Law

Question 1

What’s happens during Inertia?

Answer 1

An object will not change its motion unless acted on by an unbalanced force.
If it is at rest it will stay at rest
If it is in motion, it will remain at the same velocity

Question 2

If an object has more mass what happens to Inertia?

Answer 2

As mass increases Inertia increases so it takes more force to change their motion
As mass decreases inertia decreases so it take less force to change their motion

Question 3

What is Newtons 2nd law

Answer 3

F=ma

Question 4

What are the units for f=ma

Answer 4

F - force (N)
m - mass (kg)
A - accelerate (m/s/s)

Question 5

What’s Newtons 3rd law

Answer 5

Equal and Opposite

Question 6

How does newtons 3rd law work?

Answer 6

Forces always come in pairs
You push on a wall the wall pushes back

Action force ->
<- Reaction force

Question 7

Use Newtons Laws to explain why it is easier to turn a truck when it is empty than when it is carrying a heavy load.

Answer 7

Acceleration is the same but, it would take more force for a higher mass. Such as an heavy load. And it would take less force for less of a mass. Our full truck has more mass which means more inertia, which also means more residence to changing its motion. The empty truck has less inertia, less mass, and less resistance.

Question 8

Why would a cart with 1N on one side and 4N on the other have a bigger change in motion?

Answer 8

It would have a bigger change because the unbalanced force.

Question 9

What is the definition of Inerita?

Answer 9

Tendency to keep doing what it’s doing on resistance to changing its motion.

Question 10

If you apply an equal amount of force to two objects of different masses what object will accelerate more?

Answer 10

The object with less mass will accelerate more.

Question 11

What is a net force?

Answer 11

A net force is the sum of all forces acting on an object.

Question 12

Does mass affect the falling speed of objects?

Answer 12

No, gravity is a constant.

Question 13

The rate velocity changes with time?

Answer 13

Acceleration

Question 14

Every object persists in its state of rest or uniform motion in a straight line unless it is compelled to change that sate by forces impressed on it.

Answer 14

First Law of Motion

Question 15

Measure of gravitational attraction or force or gravity pulling one object toward the center of another object is?

Answer 15

Weight

Question 16

Push or a Pulll

Answer 16

Force

Question 17

Speed of an object but in a specific direction is

Answer 17

Velocity

Question 18

Distance traveled per unit time

Answer 18

Speed

Question 19

What’s the formula for speed?

Answer 19

Distance/time

Question 20

Amount of matter in an o Brecht or a measure or the inertia of an object

Answer 20

Mass

Question 21

Resistance to Change

Answer 21

INertia

Question 22

The force that pulls on an object and causes acceleration if the objects are not balanced by an opposing force.

Answer 22

Third law of Motion

Question 23

Force that opposes motion between two surfaces

Answer 23

Friction

Question 24

Isaac Newton developed these 3 laws concerning ..

Answer 24

Motion

Question 25

The force that prevents a ball for rolling forever

Answer 25

Friction

Question 26

The combination of all the forces acting on an object is

Answer 26

Net force

Question 27

A person steps out the boat and onto the dock. As the person moves forward onto the dock, the boat moves backward. What stamens best describe the backward motion of the boat as the person steps forward.

Answer 27

For every action there is an equal and opposite reaction.

Question 28

What to measurements are necessary for calculating speed?

Answer 28

Distance and TIme

Question 29

Which force causes an object to speed up or slow down?

Answer 29

Unbalanced force.
