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

A
Newton's first law
B
Newton's second law
C
Newton's third law

none of these

Slide 15 - Quizvraag

You throw a 0.5 kg basket ball with a force of 10 N. What is the acceleration of the ball?
A
2 m/s^2
B
10 m/s^2
C
5 m/s^2
D
20 m/s^2

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
