Can someone please help me explain what forces are acting when an apple is falling from a tree and rolling downhill. Use a similar explanation to what forces act one you when you slip over on a wet soapy floor. images are provided.
Pls answer ASAP.
Thanks

Explanation:

When an apple falls from tree , The forces acting are

( i ) Gravitation force acts downwards due to pull of the earth .

( ii ) The force of friction due to air acts upwards

When it rolls down the hill

( i )  The gravitational force due to earth acting downwards

( ii ) The force if friction due to surfaces in contact , acting upwards along the slope of the hill

When we slip on the floor

( i ) The horizontal forward force due to horizontal component of force of reaction by the floor .

( ii ) The frictional force acting in a backward direction , due to surfaces in contact .
