McCormack- Newton
McCormack-Newton's Law Test
| Answer | Question |
|---|---|
| Motion | A change in position over time |
| Speed | Distance over time (s=D/t) |
| Units for Speed | meters per second (m/s) |
| Acceleration | Change in speed over time (Vf-Vi/t) |
| Units for Acceleration | Meters per second squared (m/s^2) |
| Velocity | Speed with direction |
| Inertia | Objects in motion tend to stay in motion & objcects at rest tend to stay at rest |
| Gravity | A force of attraction based on mass and distance |
| Force | A push or pull measured in Newtons (N) |
| Acceleration due to Gravity | 9.8 m/s/s |
| Momentum | Momentum (P) = mass x Velocity P=mV Mass in motion |
| Newtons (N) | Force Units, Kg x m/s/s |
| Newton's 1st Law of Motion | Inertia, Objects at rest tend to stay at rest while objects in motion tend to stay in motion |
| Newton's 2nd Law of Motion | Force is directly related to mass & acceleration. F=ma |
| Newton's 3rd Law of Motion | Every action has and equal but opposite reaction. |
| Weight | The effect of gravity on mass Weight = mass x 9.8 m/s/s |
| Newton's 1st law of Inertia | A book sitting on the table will not move unless an unbalance force is acting on it |
| Terminal Velocity | The velocity reached when air resistance is equal to acceleration due to gravity |
| Balance Force | Equal but opposite forces that cancel out and result in no motion |
| Unbalance Force | Unequal and opposite forces that results in motion |
| Friction | A force opposite to motion resulting from the direct touch of two objects. |
| Newton's 2nd Law of Acceleration | What Law gives us the formula to calculate weight? W= 9.8m/s^2 x mass |
| Newton's 3rd Law of Action/Reaction | What Law says that book sitting on the talble has and opposite force pushing up on it? |
| Static Friction | Friction between two objects at rest |
| weight = m x g, 1,000 grams (1 kg)x 9.8 = ___9.8____ Newtons (round to 10 N) | the weight of 1,000 grams = |
| Mass | The amount of stuff in an object that cannot change based on position in the Universe |
| Newton's 1st Law, Inertia | A student flying off skate board that has hit a curb is an expamle of |
| Newton 2nd Law , F=ma, F = .1 x 2,500 = 250 N | Newton's 2nd Law of Acceleration is used to calculate the force of a bullet (.1 kg @ 2,500 m/s)F=ma |
| Newton's 3rd Law of Action/Reaction | Which Newton Law explains when a rocket engine pushes one way and rocket goes the opposite direction? |
| Newton Law of Inertia | A train takes a mile to come to a stop is an example of |
| Volume | The amount of space an object takes up, measured in Liters. |
| Calculate the weigth of a student who is 55 kg, g= 9.8 m/s2 | Weight = mg (F=ma) W = 55 kg x 9.8 m/s2 = 539 N |
| Two objects hit at the same time since acceleration of gravity is always 9.8 m/s2 on Earth | Two different mass objects dropped at the same time will |
