#### Slide 6 -Tekstslide

VISUAL CHECK- How would the net force and velocity and velocity arrows change if the girl pushed harder?

#### Slide 7 -Tekstslide

how is the object's velocity changed here?

#### Slide 8 -Tekstslide

Relate force and mass

#### Slide 9 -Tekstslide

Relate force and mass

#### Slide 10 -Tekstslide

Newton's second law of motion
Sates that the acceleration of an object is equal to the net force acting on the object divided by the object's mass.

#### Slide 12 -Tekstslide

What happens when unbalanced forces act on an object at rest?
A
the object remains at rest
B
the object begins moving in an unpredictable direction
C
the object begins moving in the direction of the net force
D
the object begins moving opposite to the direction of net force

#### Slide 13 -Quizvraag

What happens when unbalanced forces act on an object in motion?
A
the object accelerates in an unpredictable direction
B
The object accelerates in the direction of the net force
C
the object accelerates opposite to the direction of net force
D
the object always stops moving

#### Slide 14 -Quizvraag

#### Slide 16 -Quizvraag

F = ma, here F represents
F = ma, here m represents
F= ma , here a represents
force with unit Newton
m is mass with unit kg
a is acceleration unit m/s2
