Newton's Laws of Motion
Explain Newton's First Law of Motion.
A body in motion stays in motion and a body at rest stays at rest UNLESS acted on by another force.
Speed
How fast an object moves.
Explain what F=MA means.
F stands for force, M stands for mass, and A equals acceleration. This phrase means force is calculated by mass multiplied by acceleration.
Force
A push or pull that one object exerts on another.
Which force results in movement.
Unbalanced force
Explain Newton's Second Law of Motion.
Force is mass times acceleration, and the more mass and object has, the more force is needed to make it move.
Velocity
The speed and direction of a moving object.
Two carts are moving on a friction-less track. One cart is empty and one cart is full. Explain which cart needs more force and why.
The full cart needs more force because it is heavier.
Which kind of force makes things stay at rest.
Balanced force
Explain the relationship between mass and force.
The more mass something has, the more force you need to get it to move.
Weight
The measure of gravitational force between an object and the Earth.
A toy car is rolling down many different surfaces. Which surface would make it go the slowest.
Sandpaper
What two forces act on a cup to keep it balanced on table.
Gravity and the table pushing the cup up.
A ball is rolling down a hill, and it stops because of a rock. Which law explains why?
Newton's First Law of Motion.
Motion
A change in an object's position compared to fixed objects around it.
Explain why a person standing on the moon can jump higher than a person standing on the Earth.
The moon has less gravitational force.
Mr.Hill's class and Ms.Dudas's class are playing Tug Of War. Why is the rope not moving.
The classes are applying the same amount of force.
