Velocity
the speed of something in a given direction; Units measure in meters per second (m/s)
velocity
the velocity of an object does not change unless the object is acted upon by an external force
First Law
an object acted on by an unbalanced force will accelerate in the direction of the force
Second Law
forces act in equal but opposite pairs
Third Law
a change in the rate or velocity of an object; Units measure in meters per second squared (m/s^2)
Acceleration
What is an example of Velocity?
A car changing it's direction
What scientist came up with the Three Laws of Motion?
Isaac Newton
What is an example of a force in physics?
kicking a ball
What is an example of Newton's 3rd Law?
For every action, there is an equal and opposite reaction
What is an example of Acceleration?
A motorcycle that keeps moving in it's given direction.
Velocity is the magnitude of speed.
False
What is an example of Newton's first Law?
When a car is staying still and remaining still, or the car is moving and keeps moving.
What is an example of Newton's 2nd Law?
The greater the mass of an object, the more force it will take to accelerate the object

What constant measurement of speed is represented by the letter 'c'?
Speed of light
What is Newton's 1st law?
Any object in motion will continue to move in the same direction and speed unless forces act on it
Which law of motion says that the harder you kick a ball, the farther it will go?
Second Law of Motion
Which law of motion says that when you kick a ball, there is an equal force on your foot as there is on the ball?
Third Law of Motion
What is the standard unit of measurement for acceleration?
Meters per second squared
