Newtons laws of motion

Question 1

what does the newtons first law predict

Answer 1

Newton’s first law of motion predicts the behaviour of objects for which all existing forces are balanced

Question 2

what is newtons first law referred to as?

Answer 2

law of inertia

Question 3

will objects are equilibrium accelerate?

Answer 3

no they will not accelerate

Question 4

what does newtons second law of motion refer to?

Answer 4

Newton’s second law of motion refer to the behaviour of objects for which all existing forces are not balanced

Question 5

what does newtons second law state?

Answer 5

The second law states that the acceleration of an object is dependent upon two variables - the resultant force acting upon the object and the mass of the object.

Question 6

what is acceleration directly proportional to?

Answer 6

resultant force

Question 7

what is the equation of newtons second law?

Answer 7

f=ma

Question 8

when will there be a change in momentum?

Answer 8

When a force acts on an object that is moving, or able to move, there is a change in momentum

Question 9

what is the equation of momentum?

Answer 9

mass x velocity

Question 10

is momentum a vector quantity?

Answer 10

yes

Question 11

what does momentum give us an insight of?

Answer 11

gives us insight into how much force would be required to stop a moving object within a particular time frame.

Question 12

what is newtons third law according to newton?

Answer 12

According to Newton, whenever objects A and B interact with each other, they exert forces upon each other

Question 13

newtons third law chair example

Answer 13

• When you sit in your chair, your body exerts a downward force on the chair and the chair exerts an upward force on your body.
• There are two forces resulting from this interaction - a force on the chair and a force on your body.
• These two forces are called action and reaction forces and are the subject of Newton’s third law of motion.

Question 14

definition of newtons third law?

Answer 14

• For every action, there is an equal and opposite reaction.
• in every interaction, there is a pair of forces acting on the two interacting objects.
  -The size of the forces on the first object equals the size of the force on the second object.
  -The direction of the force on the first object is opposite to the direction of the force on the second object

Question 15

forces always come in pairs of ______ and ______ action-reaction force pairs

Answer 15

equal and opposite
