What is Newton's First Law?
Newton’s Second Law can be summarized using this equation.
mass = force x acceleration
force = mass x acceleration

A push or a pull is a___
force
gravity
drag
Force
A car and a train are going the same speed. The car is easier to stop because of this.
Mass
Weight
Force
It has less mass
This occurs whenever an object is acted upon by an unbalanced force.
acceleration
motion
stationary
What is acceleration
If the sum of all the forces acting on a moving object is zero, the object will
Continue moving with the same velocity
According to Newton’s Second Law, if the force increased but the mass remained the same, what happened to the acceleration?
The objects acceleration decreased.
The objects acceleration increased.
The objects acceleration is steady
The objects acceleration increased.
What is inertia?
