The basics
This law states that the acceleration of an object depends on the net force acting on it and its mass
What is newton's second law
If you push twice as hard on an object the acceleration will increase or decrease how much (if mass is not changed)
What is double
This is the unit for force
Newtons (N)
When you step on the gas pedal in a car you are increasing these quantities
What is force and acceleration
When the net force on an object is 0 then this is its acceleration
What is 0
According to Newton's Second law, this equals mass times acceleration
What is force
If two objects experience the same force, the one with less mass has...
What is greater acceleration
if a 2 kg object accelerates at 3 m/s^2, the net force is this
Hint: Force = mass * acceleration
What is 6 Newtons
This natural force gives objects their weight near Earth's surface
What is gravity
If you apply the same force to a smaller mass this happens to acceleration
What is acceleration increases
This equation represents Newton's Second Law
Acceleration always points in this direction relative to the force
What is the same direction
F = m*a can be rearranged to solve for acceleration this way:
What is a = F/m
This property of matter changes in motion
Hint: it is the reason why lighter objects are easier to move than heavy objects
What is inertia
what is gravity
What is three?
When the forces are balanced this happens to acceleration
It becomes 0
If you double the force and the mass the acceleration does this:
What is stay the same
When a baseball player hits a ball the bat exerts a force causing this to change
What is acceleration
This force opposes motion between two surfaces that are in contact
What is friction
What is a physical law
A 1000 kg car experiences a 4000 Newton force, its acceleration is this:
hint: 4000 = 1000 * a
What is 4 meters per second squared
1 Newton is the same as these base units
Hint: Base units are meters, seconds, and kilograms
What is kg*m/s^2
When you step the brakes acceleration points in this direction:
The negative direction (opposite from the direction the car is traveling)
Acceleration increases as force increases but decreases as this increases
What is mass
