Snemalna Knjiga Besedilo
Hi, i'm Lisa, and this is Alex
Were going to school,today in science class were learning about force
Force is a push or pull
were also learning about contact and non-contact forces
gravity is a non-contact force. gravity is pulling this book down to earth.
there are other non-contact forces like magnetism and electricity forces.
One contact force is Buoyancy. if I put this boat in water it would float
Friction Buoyancy applied
Friction is applied onto the electric car because the cube is heavier
Another contact force is applied force. If I put this ball on the table and push it, it will move.
