Newton's Laws of Motion

Acceleration

Rate that velocity changes over time.

Force

A push or pull on an object.

Mass

The amount of matter in an object.

Speed

Distance traveled over a certain amount of time.

Velocity

The speed of an object in a specific direction.

Gravity

A force that always pulls an object down.

Friction

A force that works in the opposite direction of the objects movement.

Motion

Movement or changing position.

Inertia

The tendency of an object to resist changes in its motion.

Object

Something being moved or moving. Something taking up space.

Equilibrium

The state when all forces acting on an object balance each other.

Newton’s First Law of Motion

An object in motion tends to stay in motion, and an object at rest tends to stay at rest unless acted upon by an outside force.

Newton’s Second Law of Motion

(F=M x A) Acceleration of an object depends on the force acting on it and the mass of the object.

Newton’s Third Law of Motion

Every action has an equal and opposite reaction.

Newton’s First Law of Motion is also known as:

the Law of Inertia.

Newton’s Second Law is also known as:

the Law of Force and Acceleration.

Newton’s Third Law of Motion is also known as:

the Law of Action-Reaction.

If an object has more mass it also has more ___________. This means that you must apply more ___________ to make the object move.

Friction

If an object has a certain mass and you want to increase its acceleration, what must you also increase

Force (F)

A ball is at rest on a table. What will happen to the ball if you don't apply any force? 

It will stay at rest.

Which of Newton’s Laws applies to this example: A ball is at rest on a table. What will happen to the ball if you don't apply any force?

Newton’s First Law of Motion - the Law of Inertia

A heavy box is being pushed by a small child, and a large adult is pushing the same box with more force. Which box will accelerate (speed up) more quickly? 

The box pushed by the large adult will accelerate more quickly because he applies more force.

Which of Newton’s Laws applies to the following?

A heavy box is being pushed by a small child, and a large adult is pushing the same box with more force. Which box will accelerate (speed up) more quickly? 

Newton’s Second Law of Motion - The Law of Force and Acceleration

A rocket launches into space. What is the action force?

The action force is the rocket's engines pushing downward against the ground making the rocket go up.

Which of Newton’s Laws explains the following?

A rocket launches into space?

Newton’s Third Law of Motion - For every action, there is an equal and opposite reaction. In this case the rocket shoots gas and fire downward, and the rocket moves up.

A bicycle is moving forward, and the rider suddenly stops pedaling. What will happen to the bicycle?

The bicycle will continue to move forward at a constant speed until acted upon by an external force, such as friction or gravity.

Which law of motion is this an example of?

A bicycle is moving forward, and the rider suddenly stops pedaling but continues moving forward.

Newton's First Law of Motion - An object in motion stays in motion unless acted upon by an external force.

You are pushing a cart with a certain amount of force. What will happen to the cart if you add more weight to it (making it heavier)

The cart will accelerate slower compared to when it was lighter.

Which law of motion applies to the following idea?

A wagon with 1 gallon of milk pulled by a little girl moves faster than a wagon with 10 gallons of milk pulled by the same girl.

This demonstrates Newton's Second Law of Motion, which states that acceleration of an object is dependent on the mass of the object and the amount of force applied. An object will accelerate more with less mass when the same force is applied.

A toy truck with a mass of 3 kg accelerates at 5 m/s/s. What is the force on the toy truck.

Using Newton's Second Law of Motion, the force is calculated by multiplying the mass of the toy truck by its acceleration, resulting in a force of 15 Newtons (F = m*a).
