Finish the sentence. If an object has a 0 Net force it will stay at rest or continue at a constant _______
velocity or speed
Final velocity = ? + acceleration x time
Initial velocity
What is the formula for momentum?
Mass x velocity

Newton's second law is Net force = Mass x ?
Acceleration
Distance = ((Initial Velocity + final velocity)/2) x ?
time
What is the most commonly used units for momentum?

If an object has a force pushing to the left of 6N and to the right of 4N, what is the net force? (Number and direction)

What is the capital city of the United Kingdom?
London
Newton's 3rd Law states that for every action there is an equal and opposite ______
Reaction
distance = ? x t + 1/2 * a * t2
Initial velocity
What is the Law of the Conservation of Momentum?
The total Momentum in a system is always conserved. Momentum can be transferred or shared to other things but the total always stays the same.
What is the name of the force that acts against the relative motion of an object?
Friction
In Newton's law of gravitation if both objects move further away from each other does the force between the objects increase/decrease or stay the same?
Decrease
In Newton's law of gravitation if both objects have a higher mass does the force between the object increase/decrease or stay the same?
Increase
Final velocity2 = initial velocity2 + 2 x acceleration x ?
distance or displacement
The total momentum of two cars before they crash is 20,000 kg.m/s2 to the right. They then crash. What is the total momentum after the crash?
20,000 kg.m/s2 to the right
What is the name given to Friction that acts from the air?
Air resistance (or air friction).
