Forces: Newtons first law.

Question 1

What is Newtons First Law of Motion?

Answer 1

• If the resultant force acting on a stationary object = 0.
• Object will remain stationary.

If the resultant force acting on a moving object= 0.
- Object will continue to move in the same direction and same speed.
(Same velocity).

Question 2

When will the velocity change?

Answer 2

• Velocity of an object will only change if there is a resultant force acting on the object.

Question 3

What does a resultant force cause?

Answer 3

• Object’s speed to change.

- Changes the object’s direction.
