Newton's First Law
State Newton's First Law
What is An object in Motion stays in motion, An object at rest stays at rest (Unless acted on by an unbalanced force)
What is in a constant force, an increase in the mass will result in a decrease in the acceleration. (Acceleration of an object is related to net force and mass)
State Newton's Third Law
What is for every action, there is an equal and opposite reaction.
What is a Vector Quantity?
When something has both magnitude and direction
Describe what will happen if you are riding a skateboard and hit a curb with the front wheels going full speed?
What happens to acceleration if the force on an object increases?
The acceleration increases.
If you push a wall with a force of 5N, how much force does the wall exert on to you?
If two People are pulling a rope in opposite directions with equal force (Say 20 newtons), what is the net force on the rope?
0 newtons (If equal, it is always 0, Ex. 20-20=0)
If you are in a car and suddenly slam on the breaks why do you jerk forward?
Inertia/Your body wants to keep moving forward.
State the equation/formula for Newtons Second Law. (Think Fnett)
If two skateboarders push off each other then what will happen (to their motion)
They will move in opposite directions but with equal forces
Newtons (N)

Is a force a push or a pull on an object?
Trick Question! It's Both!
State the other Name for Newton's First Law?
'The Law of Inertia'
If an object does NOT accelerate, what can you then say the net force acting on it is?
Net Force = 0
If you are kicking a ball, exerting force on to the ball. Is the ball also exerting force on to your foot?
Yes! Every action has equal and opposite reaction.
