Forces

Question 1

Name the scientist asscosiated with force.

Answer 1

Isaac Newton.

Question 2

What is the unit of messurment for force/weight?

Answer 2

Newtons

Question 3

What is Newton’s first law?

Answer 3

Unless acted on by a force, an object at rest will stay at rest and an object in motion will stay in motion.

Question 4

What is Newton’s second law?

Answer 4

When a force acts on a mass it accelerates. The greater the force the greater the acceleration.

Question 5

What is Newton’s 3rd law?

Answer 5

For every action there is an equal but opposite reaction.

Question 6

Desrcribe what force is.

Answer 6

Force (N) is anything capable of causing movement in a mass.

Question 7

Give examples of a force.

Answer 7

Gravity
Friction

Question 8

Describe weight.

Answer 8

Weight is the mass of an object multiplied by the acceleration due to gravity.
Weight=Mass×Gravity

Question 9

What is the unit of messurment for mass?

Answer 9

Kg

Question 10

On Earth, what is the acceleration due to gravity?

Answer 10

10m/s

Question 11

Thrust

Answer 11

Acceleration forward

Question 12

Drag

Answer 12

Deceleration due to friction with the air/ground.

Question 13

How to show an object at rest in a diagram?

Answer 13

Both arrows are equal and small.

Question 14

How to show an object accelerating in a diagram?

Answer 14

Thrust arrow is larger than drag arrow.

Question 15

How to show an object staying at a constant speed in a diagram?

Answer 15

Both arrows are equal and large.

Question 16

How to show an object decelerating in a diagram?

Answer 16

Drag arrow is larger than thrust arrow.
