What is the other name of Newton first law of motion?
who is Isaac Newton?
English polymath and mathematician.
what is Newton's third law?
Forces come in pairs- the action force and the reaction force
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.
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.
Objects with a greater mass have more or less inertia?
More inertia
how is the second law written mathematically?
F-ma
According to Newtons third law does firing a cannon push the cannon ball forward or backward?
Forward
with Balanced forces what is the net force if they do not speed up or slow down or change direction?
Zero
According to Newton unbalanced forces change what?
it can change an object's speed, direction of motion and shape.
A net force acts on it
Does more mass equal more or less acceleration?
Less
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.
If two teams are pulling on a rope with the same strength what would be the net force?
Zero
the ball will accelerate and fly through the air.
An object in motion will remain in motion unless??
a net force acts on it.
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.
Action Force
No
Does brakes on a car cause a balanced or unbalanced force?
Unbalanced force
Do object with more mass have more or less inertia?
More
what is defined to be the mass of an object times its velocity?
Momentum
what is the reaction of a spaceship engine pushes hot gas downward?
the rocket moves upward.
what kind of force is it called when an elevator is stopped on the fourth floor?
A balanced force
Does an unbalanced force cause change or no change in motion?
