In what ways does a push affect the position of an object? A push can cause an object to change its speed or direction.
What do you think are some factors in how far an object is moved with a push? Some factors include the mass of the object, the strength of the push, and the height of the ramp (slope of the path).
In what ways does a pull affect the position of an object? A pull can cause an object to change its speed or direction.
What do you think are some factors in how far an object is moved with a pull? Some factors include the mass of the object and the strength of the pull.
How does gravity affect the movement of an object? The amount of gravity is related to its mass and distance between it and another object.
If an object is on the ground, how do you know that force of gravity is working on it? If it is not moving (either up or down) but instead remaining in place, we know the pull of gravity is at work.
How does friction affect the movement of an object? Friction provides a force in the opposite direction of motion.
What kinds of materials change the amount of friction? The properties of the contacting materials, such as size or texture change the amount of friction. Rough materials will increase and smooth materials will decrease friction.
What is necessary for an object to have a magnetic force act upon it? The material should attract a magnet. The materials should be made of iron, steel or nickel.
How might you increase the amount of magnetic force on an object? Increase the strength of the magnet or hold a magnet closer.
