Forces: Newton's second law.

Question 1

What is Newtons second law of motion?

Answer 1

• The acceleration of an object is proportional to the resultant force acting to the object and inversley proportional to the mass of the object.
• Greater Force= Greater acceleration.
• Mass is larger= Acceleration is smaller.

Question 2

How do we calculate the force needed to accelerate an object?

Answer 2

• Force (N)= Mass (kg) x Acceleration m/s^2.

Question 3

What is Inertia?

Answer 3

• Object will remain stationary or move at the same speed or direction unless an resultant force is applied

Question 4

What is inertial mass?

Answer 4

• Measure of how difficult it is to change the velocity of an object.
• Ratio of the force needed to accelerate an object over the acceleration produced.
