What is Newton's First Law

An object at rest stays at rest, an object in motion stays in motion.

Every action has an equal and opposite reaction

You hit a wall with a stick. The equal but opposite reaction is _____

the wall pushes against the stick

The reason a ball bounces up when it hits the ground:

The ball exerts a force on the ground, and the ground exerts a force on the ball.

The ball and ground repel each other.

A person not paying attention while skateboarding hits a rock. The skateboard stops...they don't.

The Law of Acceleration (2nd law)

The Law of Conservation of Momentum

What is newtons 1st law

An object at rest will stay at rest, and an object in motion will stay in motion.

An object at rest will stay at rest, and an object in motion will stay in motion with a different speed and in a different direction, unless acted upon by an external force.

An object at rest will stay at rest, and an object in motion will stop immediately, unless acted upon by an external force.

An object at rest will start moving, and an object in motion will change its direction, unless acted upon by an external force.

What is Newtons 2nd law

The force acting on an object is equal to the mass of the object multiplied by its acceleration.

The force acting on an object is equal to the mass of the object divided by its acceleration.

The force acting on an object is equal to the mass of the object plus its acceleration.

The force acting on an object is equal to the mass of the object subtracted by its acceleration.

What is Newtons 3rd law

For every action, there is an equal and opposite reaction.

Every action has a greater reaction

For every action, there is a smaller and opposite reaction

Newton's 3rd law states that there is no reaction to an action

A rocket with more mass (click all that apply)

has more inertia than a rocket with less mass.

requires more force to move than a rocket with less mass.

was more difficult to move than less massive rockets.

is more stubborn than less massive rockets.

We can assume that the rockets with the least mass,

applied the most force to the ground
