Newtons First Law
What does Newtons First Law say?
An object at rest stays at rest and an object in motion will stay in motion unless a force acts on it
What does Newton's second law say?
A heavier object requires more force to move, and the more force applied, the faster it accelerates.
What does Newtons third law say?
For every action there is an equal and opposite reaction.
What is another name for Newton's first law?
The law of Inertia.
________ is the rate of change in velocity?
Acceleration
When you swim, your hands push the water backwards, which is the action. What is the reaction?
The water pushes you forward
How would the motion change?
Unless a force acts on an object.
_______ is the amount of matter in an object?
Mass
How can you tell the difference between action and reaction?
Action starts the interaction, and reaction responds to balance it out.
An object is only at rest if it has an equal what?
Same force.
What is the equation for force?
Force=mass times acceleration
How can the third law of Newton be used when you play basketball?
When a player jumps, they push against the ground, and the ground pushes them upward.
The tendency of an object to resist a change in its motion is called what?
Inertia.
What is the acceleration of a 10 kg object if a force of 50 N is applied to it?
5 m/s²
_______ is the force between objects.
Friction
