Answer:
Frictional force opposes relative motion between surfaces
Explanation:
Friction that exists when the object is not moving is called static friction. In static friction ,If we are applying a force in the object the frictional force is in the opposite direction . If it is not the case, there have been some net force and the object starts accelarating.
The main component of the contact force of two objects is normal force and that is in the perpendicular direction. Frictional force is other complnent. This frictional force is parallel to the interface between objects. Frictional force opposes relative motion between surfaces.

Answer:
4.356e-6 Newtons
Explanation:
Using the equation for the force of gravity F=
. The two masses are m1=800kg and m2=1000 kg. The value of G, the gravitational constant =6.67e-11. The problem states the distance between the center of masses of the two cars is 3.5 meters(r). Plugging in what we have from the problem, you will get 4.346e-6 newtons. This makes sense as gravity in itself is a weak force requiring extremely massive objects to result in a noticeable force.
