Mickey law (1)
When you are moving something to the other side of the room. What energy are you putting to that object?
Force
What energy does the teacup ride us?
Mass and force, The second law because of how the teacups spin.
It is easier to push an empty shopping cart than a full one why is that?
Because the full one has more mass than the empty one.This mean that more force is requied to push the full shopping cart.
When you dive off a diving board, What will happen?
You will push down on the springboard.The board springs back and forces you into the air.
If you slide a hockey puck on ice eventually it will stop. Why though?
Because of friction on the ice. It will also stop if hit something, like a player's stick or a goalpost.
Do the roller coasters at Disney world use any kind of energy?
Yes because the Legend of the Forbidden Mountain is the tallest roller coaster and it uses potential energy and kinetic energy.
What is the formula for the Second Newton Law?
It is A(acceleration)F net(net force) divided by M(mass).
The reaction of a rocket is application of the third law why?
The hot gases push against the inside tube of the rocket and escape out the bottom of the tube. As the gases move downward, the rocket move in the opposite direction.
If you kicked a ball in space, it would keep going why?
Because there is no gravity,friction or air resisting going against it. It will only stop going in one direction if it has something like a meteorite or reaches gravity field of another planet.
True or false all the roller coasters use some kind of energy.
true
The net force is the combination of?
All the forces acting on an object?
When air rushes out of a balloon, what will happen?
The opposite reaction is that the balloon will fly up.
If you are driving in your car at a very high speed and you hit something, like a brick wall or tree, What will the car do?
The car will come to an instant stop, but you will keep moving forward. This is why cars have airbags, to protect you from smashing into windscreens.
true or false, when you walk in a store and push a door are you putting force into the door to move?
True. Also, the door puts force to be heavy two.
The acceleration produced by a?
By a net force.
When a ball hits another ball really hard what will happen?
There will be a reaction to the ball the force in the ball that hit the other ball will go into the ball that is about to be hit by the other ball.
What is the first Newton Law?
Unbalanced force.
If you use the same force to push a truck and push a car, which one will have more acceleration?
The car will have more acceleration than the truck because the car has less mass.
When you jump off a small rowing boat into the water, You will push yourself forwards towards the water, But what will happen to that force?
The same force you used to push forwards will make the boat move backward.
