Force Facts
A simple push or a pull on an object.
What is Force?
The law stating that an object at rest stays at __________unless an unbalanced force acts on it.
What is REST?
How fast an object is traveling over a specific distance.
What is Speed?
The force that acts in the opposite direction of movement when two surfaces rub together.
What is Friction?
The force that pulls objects toward the center of the Earth.
What is Gravity?
This type of force occurs when two forces on an object are equal in size but opposite in direction, resulting in no movement.
What are Balanced Forces?
F = ___________ x acceleration
What is Mass?
A change in an object’s speed or direction.
What is Acceleration?
Adding this substance to a surface can reduce friction and make objects move easier.
What is Lubricant (or water/oil)?
This changes depending on where you are in the universe, while mass stays the same.
What is Weight?
This term refers to the amount of matter in an object.
What is Mass?
For every action, there is an equal and ______________reaction.
What is opposite?
A cyclist travels 25 meters in 5 seconds. This is their average speed.
What is 5 meters per second (m/s)?
The force of friction that acts on objects moving through the air.
What is Air Resistance (or Drag)?
The two factors that affect the strength of gravity.
What are Mass and Distance?
Gravity pulls objects to the __________________.
What is the center of Earth.
The property of matter that resists a change in motion.
What is Inertia?
Speed is Distance/__________________.
What is Time?
Smooth surfaces usually have ________ friction than rough surfaces.
What is less?
A person can jump higher on the moon because the moon has less ________.
What is Gravitational Pull (or Mass)?
This force causes movement.
What are Unbalanced Forces?
If you double the mass of an object but use the same force, this will happen to the acceleration.
What is it will decrease by half?
On a distance-time graph, this is represented by a horizontal straight line.
What is stopped or no motion?
This is why it is harder to stop a heavy truck than a small car moving at the same speed.
What is the truck has more mass (and therefore more inertia)?
This non-contact force can either pull opposite poles together or push like poles apart.
What is Magnetism (or Magnetic Force)?
