Chapter 10: Force And Motion

Question 1

How does the force on an object affect the objects acceleration?

Answer 1

The greater the resultant force of an object the greater the objects acceleration

Question 2

How does the mass of an object affect its acceleration?

Answer 2

The greater the mass of an object the smaller its acceleration for a given force

Question 3

What is the equation for the resultant force acting on an object?

Answer 3

Resultant force (N) = mass (kg) x acceleration (m/s squared)

Question 4

What is an objects inertia?

Answer 4

The objects tendency to stay at rest or in uniform motion

Question 5

What is the weight of an object?

Answer 5

Is the force acting on the object due to gravity. Its mass is the quantity of matter in an object

Question 6

How fast does an object accelerate due to only gravity?

Answer 6

10m/s squared

Question 7

What is the terminal velocity of an object?

Answer 7

Is the velocity it eventually reaches when it is falling, the weight of an object is then equal to the frictional force on the object.

Question 8

What is the resultant force of an object at terminal velocity?

Answer 8

The resultant force is 0
