Question 1

The greater the resultant force on an object…

Answer 1

The greater the acceleration

Question 2

The greater the mass of the object…

Answer 2

The smaller the acceleration of a given force

Question 3

Momentum

Answer 3

Mass times velocity

Kgm/s

Question 4

The resultant force acting on an object is

Answer 4

F=m a

Question 5

What is weight

Answer 5

The weigh of an object is the force acting on the object due to gravity

Question 6

What is mass

Answer 6

The quantity of matter in the object

Question 7

What acceleration does an object only affected by gravity travel

Answer 7

10m/s squared

Question 8

Inertia

Answer 8

Objects will continue with the same speed and direction unless a force acts on it

Question 9

What is terminal velocity

Answer 9

Terminal velocity is when the weight of the object is equal to frictional force on it when falling

Question 10

When an object is at terminal velocity what is the resultant force

Answer 10

Zero

Question 11

What opposes the driving force of a vehicle?

Answer 11

Friction and air resistance

Question 12

What makes up the stopping distance of a vehicle

Answer 12

Thinking distance and braking distance

Question 13

Equation for momentum

Answer 13

P= m v

Question 14

Unit for momentum

Answer 14

Kg m/s

Question 15

What is a closed system

Answer 15

The total momentum before an event is the same as the total momentum after the event

Question 16

When is an object called elastic

Answer 16

It is called elastic of its returns to its orignal shape after removing the force deforming it

Question 17

What is the extension

Answer 17

The difference between the length of the object and its orignal length.

Question 18

Extension of the spring

Answer 18

The extension of the spring is directly proportional to the force applied to it
