What does Newton's First Law of Motion state?
What is an object at rest stays at rest, and an object in motion stays in motion, unless acted upon by an unbalanced force.
What is a force?
What is a push or pull that can change the motion of an object.
What is velocity?
What is the speed of an object in a given direction.
What is gravity?
What is A force that pulls objects toward each other, such as pulling objects toward the center of the Earth.
You push a chair, and it moves. What force are you using?
What is Applied force
What is another name for Newton's First Law?
What happens to an object if the forces acted on it are balanced?
What is the object remains at rest or moves at a constant speed.
What is acceleration?
What is the rate of change of velocity over time.
What is Mass?
What is The amount of matter in an object.
A ball rolling on the ground eventually stops. What force caused it to stop?
What is friction.
What formula is associated with Newton's Second Law?
What is Force =Mass x Acceleration (F=ma)
What is A force that opposes the motion of objects when they rub against each other
What is inertia?
What is the tendency of an object to resit changes in its motion.
How is weight different from mass?
What is Weight is the force of gravity acting on an object's mass.
You jump off a diving board, and the diving board pushes you up as you go down, Which law is this an example of?
What is Newton's Third Law
Explain Newton's Third Law of Motion.
What is for every action, there is an equal and opposite reaction.
What are unbalanced forces?
What is Forces that do not cancel each other out, causing a change in an object's motion.
What is the difference between speed and velocity?
What it Speed is how fast something is moving, while velocity includes both speed and direction.
How does the force of gravity change with distance?
What is gravity gets weaker as the distance between objects increases.
A book stays still on a table until you push it. Which law is this an example of?
What is Newton's First Law
How does Newton's Second Law relate to the acceleration of objects with different masses?
What is objects with more mass require more force to accelerate than objects with less mass.
How does Friction affect motion?
What it it slows down or stops the motion of objects that are in contact with each other.
How do you calculate acceleration?
What is Acceleration = (final velocity- initial velocity) / time
Why do objects with more mass have a stronger gravitational pull?
What isbecause the force of gravity depends on the mass of the objects, with more massive objects exerting more force.
A person pulls on a heavy wagon. What two forces are at work, and how do they interact?
What is applied force (person pulling) and friction (between wagon and the ground, resisting motion)
