dynamics

Question 1

Newton’s Third Law of Motion

Answer 1

when body A exerts a force on body B, body B will exert an oppositely directed force of the same type of equal magnitude on body A

Question 2

Newton’s First Law of Motion

Answer 2

an object continues to be in a state of rest or in motion with a constant velocity, unless acted upon by a net external force

Question 3

Linear momentum

Answer 3

product of its mass and its velocity

Question 4

Newton’s Second Law of Motion

Answer 4

the rate of change of momentum (effect) of a body is directly proportional to the resultant force (cause) acting on it and takes place in the direction of the resultant force

Question 5

Impulse of a force

Answer 5

the product of the average force and the time interval during which the force acts

Question 6

Principle of Conservation of Linear Momentum

Answer 6

the total linear momentum of a system remains constant provided that no resultant external force acts on the isolated system
