Sometimes tectonic plates do not move easily past one another, and the plates become stuck. Forces build up, and when the plates finally move, tension is released, as shown below. The sudden movement of the plates is caused by -

• the mass of the plates

• the weight of the plates

• unbalance forces

• gravitational force

Which of the following statements best describes Newton's First Law of Motion?

• An object will remain at rest or in uniform motion in a straight line unless acted upon by an external force.

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

• For every action, there is an equal and opposite reaction.

• The force of gravity acts between all masses.

According to Newton's Second Law of Motion, what is the formula for calculating force?

Newton's Third Law of Motion states that:

• The force of gravity is the same for all objects.

• The acceleration of an object is directly proportional to the net force acting on it.

• For every action, there is an equal and opposite reaction.

• An object will remain at rest unless acted upon by an external force.
