🗑
|
||||
| If you push a steel ball (25g) and a wooden ball (2.5g) with the same force, which ball will accelerate faster? | The wooden ball. It has less mass.
🗑

||||
| What is the main force that stops a ball rolling across carpet? | Friction
🗑
|
||||
| Which law explains that it will take a lot more force to move an elephant than it will to move a squirrel? | Newton's second law of motion
🗑
|
||||
| Kinetic energy | Energy that an object has as a result of its motion.
🗑
|
||||
| Potential energy | Energy that is stored.
🗑
|
||||
| Momentum | Property of matter due to its mass and velocity.
🗑
|
||||
| Friction | Force that opposes motion or resistance caused when two surfaces touch or rub together.
🗑
|
||||
| Distance | How far an object is from one point to another.
🗑
|
||||
| Energy | Ability to do work or cause change.
🗑
|
||||
| Speed | Rate at which the position of an object changes.
🗑
|
||||
| Action-reaction forces are equal in strength and _____ in direction. | Opposite
🗑
|
||||
| As a car rolls down a ramp, it loses potential energy and gains _____ energy. | Kinectic
🗑
|
||||
| True or false? When a car rolls down a hill its speed increases. | True
🗑
|
||||
| In a spring jumper, what provides the action force? | Spring
🗑
|
||||
| In a spring jumper, what provides the reaction force? | Table
🗑
|
||||
| Air resistance | The force exerted by air against an object moving through it and acts in the opposite direction of the object's motion
🗑
|
||||
| Parabola | The downward curve that is created by gravity when an object is thrown horizontally
🗑
|
||||
| All objects appear to 'float' in orbit because of _____. | Free fall
🗑
|
||||
| Microgravity | A term used to describe the almost weightless condition in space.
🗑
|
||||
| A flat piece of paper and a crumpled piece of the same paper are dropped from a height of 4 feet. Which one will fall faster? | Crumpled sheet of paper
🗑
|
||||
| Why would a crumpled sheet of paper fall faster than a flat sheet of paper if both pieces of paper are the same size? | The crumpled sheet of paper has less surface area. Therefore, the crumpled sheet has less drag/air resistance.
🗑
