Forces
This is a force that slows or stops motion when objects rub together.
What is friction.
Newton's first law is called this.
What is the Law of Inertia?
This law explains why a person riding in a car will continue to move forward when the car stops.
What is Newton's 1st Law?
This simple machine allows you to spread out work by walking a longer distance.
What is inclined plane? (ramp)
The fixed point on a lever is called this.
What is fulcrum?
This force is a push or a pull.
What is applied force?
Newton's 2nd law says that the acceleration of an object increases with this.
What is force?
Newton's 1st Law states that an object at rest will stay at rest and an object in motion will stay in motion unless acted upon by this.
What is unbalanced force?
This simple machine is a consists of a bar that pivots on a fixed support. It is used to lift a load.
What is a lever?
This type of motion is without change in speed and direction.
What is uniform motion?
This is force is a pull between two objects. The larger the object, the more of this type of force it has.
What is gravity?
Newton's third law is know as this.
What is Action-Reaction Law?
This law explains how a rocket is able to lift off the ground.
What is Newton's 3rd Law.
This simple machine is thick on one end and thin on the other. It is driven between two objects to secure or split apart.
What is a wedge?
This type of force acts at a distance. An example of this type of force is magnetic force.
What is non-contact force?
In magnetic force, opposite poles do this.
What is attract?
What is decreases?
This law explains why a 300 lb man running at 5 mph is harder to stop then a 100 lb man running at 5 mph.
What is Newton's 2nd Law?
What is force?
This happens when balanced forces are applied to an object in the same direction.
What is the object moves?
Force is measured in this.
What is a newton?
What is equal and opposite reaction?
This is the formula for Newton's 2nd Law.
What is F (force) = m (mass) multiplied by a (acceleration)?
A wheelbarrow is made up of these two simple machines.
What are a lever and a wheel and axle.
This describes the amount force being applied to the car in this situation....
A 100 kg car is being pushed 3 m/s.
What is 300 Newtons?
