Making Movement Happen
These forces cause acceleration because one is larger than the other.
What are unbalanced forces?
This force opposes motion.
What is friction?
Newtons 1st Law
What is an object in motion will stay in motion, an object at rest will stay at rest until acted upon by an unbalanced force?
This is Newton's 2nd law.
What is F=ma?
Newtons 3rd Law
What is: for every action, there is an equal, and opposite reaction.
These forces cause an object continue its current motion.
What are balanced forces.
Anything with mass has this force. It is a pulling force.
What is gravity.
This is another name for Newtons 1st Law.
What is Inertia?
If the force increases, acceleration will do this.
What is increase?
This is why a balloon flies around the room when you let the air out.
What is the air pushed out, then pushes the balloon forward?
Two dogs are pulling on a shoe. The dog on the left is pulling with 20N of force and the dog on the right is pulling with 20N of force. This is the net force.
What is 0N?
This is the measure of the pull of gravity on an object.
What is weight?
If you run and jump, this will happen.
What is you will land farther forward than where you started?
If the the mass decreases, acceleration will do this.
What is increase?
A student pushes on a wall. This is why the wall did not move.
What is the wall pushed back on the student.
A soccer ball is kicked with 10N of force to the left. A fan is on the left, blowing the soccer ball with 20N of force. This is the net force.
DO NOT FORGET DIRECTION!!
What is 10N to the right?
When you go to a different planet, your weight does this.
What is changes?
When a magician pulls a table cloth from a table the dishes do this.
What is stay in place?
If an object has a mass of 10kg, this is its weight on earth.
Acceleration due to gravity on earth is 9.8m/s2
What is 98N?
When a rocket takes off, this is the reaction force.
What is the exhaust pushes back on the rocket?
This is what we call action/reaction forces. They are not balanced because they do not cancel each other out.
What are paired forces?
When you go to a different planet, your mass does this.
What is stays the same?
This is another example of Inertia.
What is ...?
A car has a mass of 10,000kg. This is how much force it would take for it to accelerate from a stop sign to 60km/h in 30 seconds.
What is 1,200,000N?
A swimmer pulls on the water with 10N of force. This is how much force the water pushes him forward with.
What is 10N of force?
