We use speed, velocity and acceleration to describe motion.
How is mass different from weight?
Mass = amount of matter. Weight = force of gravity on matter.
How did Newton change our view of the universe?
Newton discovered that physics are the same in space as they are on Earth.
What are Newton's three laws of motion?
1 An object moves at a constant velocity unless a net force acts to change its speed or direction. 2 Force = mass x acceleration. 3 For every force their is an equal and opposite reaction force.
When was Isaac Newton born?
1642.
When did Galileo Galileo die?
1642.
Is the First Law of Motion still valid?
Yes.
What is speed?
Speed = distance/time.
What is velocity?
Velocity = speed and direction.
What is acceleration?
Acceleration = change in velocity.
