Forces And Pressure (3)

Question 1

Newton’s First Law of Motion

Answer 1

States that every object will continue in its state of rest or uniform motion in a straight line unless a resultant force acts on it

Question 2

Newton’s Second Law of motion

Answer 2

States that when a resultant force acts on an object of a constant mass, the object will accelerate in the direction of the resultant force. The product of the mass and the acceleration of the object gives the resultant force.

Question 3

Newton’s Third Law of Motion

Answer 3

States that if body A exerts a force on body B, then body B will exert an equal and opposite force on body A

Question 4

Friction

Answer 4

The contact force that opposes or tends to oppose motion between surfaces in contact

Question 5

Pressure

Answer 5

The force acting per unit area
