Question | Answer |
You can increase acceleration by increasing this. | Force |
What does Newton's 2nd Law state? | The acceleration of an object depends on the object's mass and the net force acting on it. |
What are the two formulas for acceleratiion? | net force / mass and (final velocity - initial velocity) / change in time |
What is the formula for force? | mass * acceleration |
What are the units for force? | Newtons and kg * m/s^2 |
What does Newtown's 3rd law state? | For every action, there is an equal and opposite reaction. |
What is the formula for momentum? | mass * velocity |
What is the unit for momentum? | kg * m/s |
Movement results from this type of force: | unbalanced |
What is terminal velocity? | When an object reaches its greatest velocity while falling. When the force of air resistance = the weight of the object. |
Formula for speed: | Distance / time |
Formula for distance: | speed * time |
Formula for time: | distance / speed |
Three ways an object can accelerate: | speed up, slow down, change direction |
What is a balanced force? | Opposing equal forces that cancel each other out. |
What are the two ways to increase the acceleration of an object? | Increase force or decrease mass. |
Why would an object have more inertia? (Newtown's 1st Law) | Because it has more mass, and the more mass an object has, the more inertia it has, and the harder it is to start and stop. |
