6.5.4.2.1 newton’s first law

Question 1

Newton’s first law states that if the resultant force acting on an object is zero and :
The object is stationary, the object remains..?
The object is moving, the object continues .. and in the same direction. So the object continues to move at the same velocity,

Answer 1

It remains stationary.
the object continues moving at the same speed and in the same direction.

Question 2

When a vehicle travels at a steady speed the resistive forces are what to the driving force?

Answer 2

Balanced, equal etc.

Question 3

The velocity (speed and/or direction) of an object will only change if..

Answer 3

a resultant force is acting on the object.

Question 4

What is inertia

Answer 4

the tendency of objects to continue in their state of rest or of uniform motion.
