LFE

Question 14

Second Class lever

Answer 14

FLE - Load is always bigger than the effort - Mechanical Advantage

Question 15

Third Class lever

Question 16

Newtons first law

Answer 16

When there is zero net force acting on an object the object is stationary or remaining at a constant velocity.

Question 17

Law of inertia

Answer 17

A massive object will remain at rest and will require a force to shift it and once moving will require a force to change its motion.

Question 18

Newtons second law

Answer 18

Bigger the force,the greater the acceleration of the person.
A stronger sprinter should be able to accelerate
The more mass an object has,the more acceleration for a given force.
F = M x A

Question 19

Newtons third law

Answer 19

For every reaction there is an equal and opposite reaction.
