100
Newton's second law of motion.
What is an object with mass accelerates when an unbalanced net force is applied to it?
What is Fnet = m x a?
100
The type of force needed for Newton's second law of motion to occur.
What is an unbalanced force?
100
The acceleration of a wagon that has a mass (m) of 20kg, and is being pulled with a net force (Fnet) of 50N.
What is 2.5 m/s2?
200
The variables and units for each of the variables involved in Newton's second law of motion.
What is:
Mass (m) = kg
Acceleration (a) = m/s2
Net force (Fnet) = N
200
The two types of unbalanced forces.
What is a push and a pull?
200
The acceleration of a wagon that has a mass (m) of 20kg, and is being pulled with a net force (Fnet) of 100N.
What is 5m/s2?
300
The formula for each variable in Newton's second law of motion.
What is:
Fnet = m x a
a = Fnet/m
m = Fnet/a
300
A handstand represents a _________ force.
What is a balanced force because the person is staying still?
300
An object accelerates at 6 m/s2. What is the acceleration if the mass is doubled?
What is 3 m/s2?
400
The relationship between force and acceleration when mass remains the same.
The result of the force quadrupling (x4) on acceleration.
What is a directly proportional relationship?
What is the acceleration will quadruple, as well?
400
The image below represents a _________ force, as the dog pulls with 80N of force, and the person pulls with 20N of force. 
What is an unbalanced force?
400
The reason why a rocket moves slowly at takeoff before rapidly accelerating through the atmosphere.
What is because the rocket loses mass as it burns fuel, so it is able to accelerate (mass decreases, acceleration increases)?
500
The relationship between mass and acceleration when net force remains the same.
The result of the mass tripling (x3) on acceleration.
What is an indirectly proportional relationship?
What is the acceleration will be divided by three?
500
The type of force that keeps our bodies on the ground.
What is gravitational force?
500
The acceleration of an object that was originally moving at 10 m/s2, before its force was doubled, and mass was quadrupled.
What is 5 m/s2?
