What force does the ground produce that makes it difficult to push things on the ground?

• Friction

• Gravity

• Density

What direction is the present going?

• right

• left

Tags

NGSS.MS-PS2-2

The present moves to the right because

• The applied force is bigger than the friction force

• The friction force is greater than the applied force

• The applied force and the friction force are the same
