Question 1

Weight

Answer 1

gravitational force exerted on an object

Question 2

Inertia

Answer 2

tendency of an object an object to resist any change in it’s motion

Question 3

Friction

Answer 3

force that opposes the sliding motion between two touching surfaces

Question 4

Matter

Answer 4

anything that takes up space that has matter

Question 5

Net Force

Answer 5

sum of all of the forces that are acting on an object

Question 6

Unbalanced Forces

Answer 6

a force that causes a change in motion

Question 7

Balanced Forces

Answer 7

a force that doesn’t cause a change a motion; net force is zero

Question 8

Newton’s First Law

Answer 8

states that an object moving at a constant velocity keeps moving at the velocity keeps moving at the velocity unless an unbalanced force acts on it

Question 9

Newton’s Second Law

Answer 9

states that the acceleration of an object is in the same direction as the net force on an object

Question 10

Newton’s Third Law

Answer 10

states that when one object exerted a force on a second object, the second object exerts a force on the first object

Question 11

What is the formula for Net Force?

Answer 11

Net Force( Newtons) = Mass(kg) x Acceleration(m/s)

Question 12

True of False, is friction a force?

Answer 12

True
