Newton's Laws Of Motion

Question 1

What is newton’s first law?

Answer 1

If the resultant force acting on an object is zero, then it’s acceleration will be zero

Question 2

What is newton’s second law?

Answer 2

An object will accelerate if there is a resultant force acting upon it

The acceleration of the object is:
Proportional to the resultant force acting on it
Inversely proportional to its mass

F=ma
F=resultant force
Mass=kg, inertial mass

Question 3

What is inertia?

Answer 3

The tendency of an object to remain at rest or at constant velocity

Question 4

What is newton’s third law?

Answer 4

When an object exerts a force on another object, the second object will exert an equal and opposite force on the first. Both forces must be of the SAME TYPE

Question 5

What pairs can’t be the same time?

Answer 5

Non Contact and contact forces

Question 6

What is used for the practical?

Answer 6

Trolley, data logger, light gate, pulley and some masses

Question 7

What is equation used for the practical?

Answer 7

Average velocity=length of flag/time

Question 8

Whare the dependent, independent and control variables?

Answer 8

Dependent=1. Acceleration 2.acceleration
Independent=1. Resultant force 2. Mass
Control variable=1. Mass 2. Resultant force
