Question 3

Newton

Answer 3

Unit for measuring forces

Question 4

Resultant force

Answer 4

Question 8

Hooked law

Answer 8

Hookes law Says that the extension of the spring is directly proportional to the force on the spring

Question 9

Newton’s first law

Answer 9

If the resultant force of an object, zero, stays at rest, if it is stationary, or keeps moving with the same speed in the same direction

Question 10

Newton’s second law

Answer 10

F=ma
Where F= unbalanced force (N) m= mass and a=acceleration

Question 11

Newton’s third law

Answer 11

When two objects interact with each other, they exert equal and opposite forces on each other
