Force and Newton’s Laws

Question 1

What is thrust?

Answer 1

Thrust is the force that prevents 2 objects from coming together

Question 2

What is tension?

Answer 2

Tension is the force that prevents 2 objects from moving away from each other

Question 3

What is weight?

Answer 3

Weight always acts vertically downwards; it measures the size of the pull of gravity on an object

Question 4

What is resistance?

Answer 4

Resistance is a force that opposes the motion of a particle

Question 5

What is friction?

Answer 5

Friction is the resistance that one surface or object encounters when moving over another

Question 6

What is reaction?

Answer 6

Reaction is when 2 objects come into contact and each exert a force on the other. Direction is perpendicular to surface of contact

Question 7

What is equilibrium?

Answer 7

Equilibrium is the state of rest or moving with a constant velocity; resultant force must be 0

Question 8

What does Newton’s 1st Law state?

Answer 8

The 1st law states that an object at constant velocity will remain at constant velocity unless unbalanced forces are acted upon the object
