Unit 2: newtons Laws Of Motion

Question 1

Newtons First Law Of Motion

Answer 1

An object will remain at rest or motion at constant velocity, unless acted upon by an external net force

Question 2

Inertia

Answer 2

Inertia is the resistance of an object to a change in its state of motion or rest

Question 3

Acceleration

Answer 3

Acceleration is the rate of change of an object

Question 4

Newtons Second Law Of Motion

Answer 4

If a met force acts on an object, the object will accelerate in the direction of the met force. The acceleration is directly proportional to the met force and inversely proportional to the mass of the object

Question 5

Newton As The Unit Of Force

Answer 5

One newton is the force that accelerates a mass of 1kg at 1m/s-2

Question 6

Newtons Third Law Of Motion

Answer 6

If object A exerts a force on object B, Object B simultaneously exerts an oppositely directed force of equal magnitude
