Mechanics

Question 1

Force

Answer 1

anything that can cause an object to accelerate

Question 2

Mass

Answer 2

the mass of an object is a measure of how difficult it is to move that object
OR
the mass of an object os a measure of its inertia

Question 3

acceleration

Answer 3

the rate of change of the velocity of an object with respect to time

Question 4

velocity

Answer 4

the rate of change of displacement with relation to time

Question 5

displacement

Answer 5

the straight line distance between two points

Question 6

Newton’s first law of motion

Answer 6

Newton’s First law of motion states that every object will remain in a state of rest or travelling with a constant velocity unless an external force acts upon it

Question 7

Newton’s second law of motion

Answer 7

Newton’s second law of motion states that the rate of change of an object’s momentum is directly proportional to the force which caused it, and takes place in the opposite direction of the force.

Question 8

Newton’s third law of motion

Answer 8

Newton’s third Law of motion states that when body A exerts a force on body B, B exerts a force that is equal in magnitude but opposite in direction.

Question 9

Speed

Answer 9

the rate of change of distance with respect to time

Question 10

acceleration due to gravity

Answer 10

9.81 m/s^2
