First Law of Motion
What is Newton's first law of motion?
an object at rest will stay at rest and an object in motion will stay in motion
What is Newton's seccond law of motion?
the more force applied the faster an object can move, and the heavier an object is more force will be needed to move it
What is Newton's Third Law of motion?
for every action there is an equal and opposite reaction
What is Kinetic Energy?
What is force?
push or pull on objects
If an object is set on a table what will it do?
stay at rest on the table
What will require more force to move? A feather or a brick?
brick
What happens when one object pushes on another?
The first object pushes on the second object, and the second object pushes back on the first object with the exact same amount of force.
What is Potential Energy?
the energy stored in an object that can be released
What force keeps things on the ground?
gravity
If an object is moving in space what will it do?
keep moving
If two people push two identical chairs and one person runs and the other person walks, whose chair moves faster?
the one who is running
What do we call the two forces in newtons third law of motion?
action force and reaction force
When you raise an object up what energy does the object gain?
potential energy
What force causes roller coasters to stop?
friction
What would cause a resting object to not rest anymore?
a force being applyed causing the object to move
If a bick and a pebble are being pushed and are going the same speed, which object has more force being applied?
the brick
Do the pushes happen in the same direction?
No, they always happen in opposite directions! If you push forward, the other object pushes back backward.
When you drop an object what energy does it gain?
kinetic energy
What force gives rollercoasters energy?
gravity
What causes a kicked ball to stop moving across the ground?
a force that is applied that causes the ball to stop
What is the equation for Newton's seccond law of motion?
F = m*a
When you bounce a ball, what happens?
You push the ball down towards the ground (action), and the ground pushes the ball right back up to you (reaction)! That's why it bounces!
When you drop an object what energy does the object lose?
potential energy
When you are riding a roller coaster what is the force that helps keep your car on track and that you feel?
G-force
