What is the other name of Newton first law of motion?

Law of Inertia
100

who is Isaac Newton?

English polymath and mathematician.

100

what is Newton's third law?

Forces come in pairs- the action force and the reaction force

100

what is a balanced force?

when two or more individual forces acting on an object are equal in strength and opposite direction causing the net force to equal zero.

100

what is an unbalanced force?

a push or pulling act on an object that does not have equal and opposite force to cancel it out.

200

 Objects with a greater mass have more or less inertia?

More inertia

200

how is the second law written mathematically?

F-ma

200

According to Newtons third law does firing a cannon push the cannon ball forward or backward?

Forward

200

with Balanced forces what is the net force if they do not speed up or slow down or change direction?

Zero

200

According to Newton unbalanced forces change what?

it can change an object's speed, direction of motion and shape.

300
An object at rest will remain at rest unless what?

A net force acts on it

300

Does more mass equal more or less acceleration?

Less

300

When a person hits a baseball with a bat, the bat exerts a force of the ball. What is the reaction force?

The ball exerts an equal and opposite force on the bat. 

300

If two  teams are pulling on a rope with the same strength what would be the net force?

Zero

300
According to unbalanced forces when you kick a ball that is stationary what will happen to the ball?

the ball will accelerate and fly through the air.

400

An object in motion will remain in motion unless??

a net force acts on it.

400

According to Newton's second law, what is the relationship between the net force applied to an object and the resulting acceleation?

They are proportional in meaning that doubling the net force doubles the acceleration.

400
When walking and your foot pushes backwards again the ground is that an action force or a reaction force?

Action Force

400
Can an object be moving if the forces acting on it are balanced?

No

400

Unbalanced force

500

Do object with more mass have more or less inertia?

More

500

what is defined to be the mass of an object times its velocity?

Momentum
