Law Of Motion

Question 1

What is the 2nd law?

Answer 1

Force equals mass times acceleration

F=m•a

Question 2

What is the 3rd law?

Answer 2

For every action there is an equal and opposite reaction

Question 3

What is inertia?

Answer 3

The tendency of an object to resist changes in to velocity: whether in motion or not

Question 4

What force do we not see?

Answer 4

Friction

Question 5

What’re the 4 main types of friction?

Answer 5

Sliding type (ice skating)

Rolling friction (bowling)

Fluid friction (air or water resistance)

Static friction (ignition friction when moving an object)

Question 6

What is the equation for the 2nd law?

Answer 6

F=m•a

Question 7

What is the net force of an object equal to?

Answer 7

The product of its mass and acceleration or f=ma

Question 8

What is the acceleration when mass is in kilograms

Answer 8

M/s^2 and the unit of force is in newtons

Question 9

What does newtons 2nd law prove?

Answer 9

The different masses accelerate to the earth at the same rate, but with different forces

Question 10

What do objects with different masses accelerate to the ground?

Answer 10

At the same rate

Question 11

If two objects have different masses would the hit at the same time?

Answer 11

No

Question 12

What is the 1st law of motion

Answer 12

An object at rest will stay at rest

An object in motion sill stay in motion unless acted upon by an unbalanced force
