#### Slide 9 -Tekstslide

Inertia- Newton's first law of motion states that "An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force."

#### Slide 12 -Tekstslide

Acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object.

CONCEPT CHECK

#### Slide 14 -Tekstslide

For every action, there is an equal and opposite reaction.

A
Balance
B
Unbalance
C
Inverse
D
Proportional

#### Slide 35 -Quizvraag

An object is initially at rest on a frictionless surface. We apply a force of 1 Newton to the right.
What happens?
A
Object pushes back with equal force. Object stays motionless
B
Object starts moving to the right and slows down eventually
C
Object starts to acceerate to the right
D
Object starts moving to the right and continue moving with a constant speed
