Use the Force Luke
These change the shape of an object, its speed, or the direction it's moving in.
What are forces?
Newton's law that states "For every force, there is an equal and opposite reaction force."
What is Newton's third law?
The force on an object caused by another object in direct contact.
What is an applied force?
It's the amount of matter in an object. It's often measured in kilograms in the metric system.
What is mass?
If an object is at rest and friction is holding it in place, the object will resist a change in motion. This is the tendency to resist that change.
What is inertia?
This force occurs between objects that are not in direct contact.
What is a non-contact force?
The tendency of an object to stay in its current state of motion is known as inertia. This is the basis for this law.
What is Newton's First Law?
This contact force pushes back on a moving object and transfers the object's energy to heat.
What is friction?
The gravitational force exerted on an object.
What is weight?
This type of friction opposes the motion of surfaces sliding past each other.
What is sliding friction?
This force is a non-contact force, and acts upon any object in it's field that has mass.
What is a gravitational force?
This law states that the rate of change of momentum of a body over time is directly proportional to the force applied, and occurs in the same direction as the applied force.
What is Newton's second law?
This force resists deformation.
What is a restoring force?
Two objects have the same Velocity. However, one has greater momentum due to this.
What is greater Mass?
A space craft encounters this kind of friction during re-entry.
What is Fluid Friction or Air Resistance?
This force acts upon a charged object when placed within its field.
When a rocket fires in space it is still propelled forward despite no atmosphere to push against because of this law.
What is newton's third law?
When net force on an object is 0 Newtons the forces are said to be this.
What is balanced?
The combination of all forces acting on an object.
What is the Net Force?
The kind of friction that prevents surfaces from sliding past each other.
What is static friction?
This force will act upon any object within its field, but only if the object is made of magnetic material.
What is a magnetic force?
Issac Newton devised the three law's of motion while at his family's country estate in England. He got the idea while studying under a tree and this fell on him.
What is an apple?
When the net force applied to an object is higher on one side, the forces are said to be this.
What is unbalanced?
In circular motion, it is a force that acts perpendicular to the direction of motion.
What is Centripetal Force?
Friction between a surface and a material that flows, such as air or water.
What is fluid friction?
