| Question | Answer |
|---|---|
| Sir Isaac Newton graduated from what University? | Cambridge University |
| Sir Isaac Newton’s theories are based on what type of science? | The basis of the Laws of Motion and definition of forces |
| What happens when you add additional forces to the original force? | Force is added and combined forces act in the same direction. |
| In Newton’s law, two forces of equal strength act as what? | On the same object in opposite direction |
| In plain basic understanding of the 3rd Law, what does it mean? | The forces are equal in strength, but opposite in direction. |
| What is Newton’s 3rd Law? | One object exerts force on a second object and the second object on the first |
| What is Newton’s 2nd Law? | Newton’s 2nd Law is force equaling mass times acceleration. Force=Mass X Acceleration |
| What is the differences between inertia in large and small objects? | Large, heavy objects have more inertia than small, lighter objects |
| What is inertia? | It’s the tendency of an object to resist any change in motion |
| What is Newton’s 1st Law? | An object at rest will stay at rest An object in motion will keep the same speed and direction. |
| What does Uniform in motion mean? | It means the speed in an object stays the same |
| What is known as motion without acceleration? | Uniform motion |
| What is known as the rate of speed in an object? | Acceleration |
| What are the three motions that change in an object? | Speed up, Slow down, or changes direction |
| What is made of two inclined planes and used to push objects apart? | A wedge |
| What is an inclined plane wrapped in a spiral? | A screw |
| What uses wheels and a rope to raise, lower, or move a load? | A pulley |
| What is used to carry loads around easily for long distances with less effort? | A wheel and axle |
| What is any slope or ramp that makes it easier to lift something? | An inclined plane |
| What is a rod balanced on a fixed point that can help lift a heavy weight with less effort? | A Lever |
| What are the two magnetic forces that pull together in a magnet and that repel from each other in a magnet? | N to S or S to N = pull together N to N and S to S = repel each other |
| What are forces that pull together or push away due to their north or south magnetic poles? | Magnetic Forces |
| What are forces between objects that are electrically charged? | Electric Forces |
| What is non-contact force, it pulls objects towards itself, like the Earth? | Gravity |
| What are the three non-contact examples? | Magnetic forces, Electric forces, & Gravity |
| What is a type of force that acts as a distance? | Non-contact |
| What is the force that results when two materials rub against each other? | Friction |
| What force is known as either pushing or pulling an object? | Contact Force |
| What is force measured in units of? | Newtons |
| What is defined as the push or pull that acts on an object? | Force |
