• The gravitational Force

Nora is trying to pull her small boat down to the sea from the beach. She pulls with a force of 2000N, but the boat does not move. What was the value of friction at this moment?

• Greater than 2000N

• Equal to 2000N

• Less than 2000N

• There is no friction

Match the following

• Friction

• An object at rest remains at rest, and an object in motion remains in motion at a constant speed and in a straight line unless an unbalanced outside force is acting on it

• inertia

• for every action (force) in nature there is an equal and opposite reaction. If object A exerts a force on object B, object B also exerts an equal and opposite force on object A.

• Newton's First Law

• The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass

• Newton's Second Law

• a property of matter by which it continues in its existing state of rest or uniform motion in a straight line, unless that state is changed by an external force.

• Newton's Third Law

• the resistance that one surface or object encounters when moving over another.
