Understanding Newton's 1st Law
An object at rest ......
What is stays at rest unless an external force acts on the object.
What is inertia?
What is an object's resistance to change its current state of motion?
Forces that are equal in size but opposite in direction, they cancel eachother out, resulting in no change of motion.
What are balanced forces?
Pushes or pulls that come from outside an object.
What are external forces?
A book sitting on a a table stays there until someone picks it up. What part of Newton's 1st law is being represented.
What is an Object at rest stays at rest unless acted on by an external force?
An object in motion....
What is stays in motion at a constant velocity unless an external force acts on the object?
Objects in motion resist what according to the law of inertia?
What is changing speed, stopping or changing direction?
What are Unbalanced Forces?
Direct pushes or pulls.
What are applied forces?
Kicking a soccer ball.
What is an unbalanced force?
An object at rest will resist what according to the Law of Inertia.
What is resist being put in motion?
A box is sitting motionless on the floor. Are the forces balanced or unbalanced?
What is a Balanced Force?
Force pulling objects toward Earth.
What is Gravity?
A boat moving at a constant velocity.
What happens to a moving object if no external forces act on it?
What is it will continue at a constant velocity?
What is Mass?
What type of forces cause an object to start moving from rest?
What are unbalanced forces?
Force that opposes motion.
What is Friction?
It is harder to push a shopping cart full of groceries than an empty one. What explains this?
An object at rest has a constant velocity of.....
What is 0?
Why do you feel pushed back in your seat when a car accelerates quickly?
What is your body's inertia wants to resist the change of motion?
What Net Force does a Balanced Force have in motion and at rest?
What is a net force of 0?
If a book is pushed on a frictionless surface, what will happen to the book's motion?
What is the book will continue at a Constant Velocity?
A hockey puck slides across ice and eventually stops. What external force caused it to stop?
What is Friction?
