Play through this interactive game to learn about Factors Influencing Motion : Newton's First and Second Laws. Suitable for Grade 6, Grade 7, Grade 8.

Main Concepts

A force is a push or pull on an object.(MS)

A force is a vector quantity with magnitude and direction.

A position-time graph shows how the position of an object changes over time.

A velocity-time graph shows how the velocity of an object changes over time.

Acceleration is a measure of the change in velocity of an object over an interval of time.

Acceleration is a vector quantity with a magnitude and direction.

An unbalanced force can cause a change in the direction in which an object travels.

An unbalanced force can cause a change in the position of an object.

An unbalanced force can cause a change in the speed of an object.

Average speed is defined as the distance an object travels divided by the time it takes to travel that distance.

Inertia is the tendency of an object to resist a change in motion.

Newton's first law of inertia can be observed in different applications.

Newton's first law states that the motion of an object will remain constant unless it experiences an unbalanced force.

Newton's second law can be observed in many common applications.

Newton's second law states that the acceleration of an object is proportional to the net force acting on it and inversely proportional to its mass: a = F/m.

Objects move in the direction in which an unbalanced force acts.

Objects with greater mass have greater inertia.

The forces acting on an object are unbalanced when there is a net force acting on it.

The forces on an object are balanced when there is zero net force acting on it.

The slope of a curve on a position-time graph gives the velocity of the object.

The slope of a curve on a velocity-time graph gives the acceleration of the object.

The sum of all forces acting on an object is called net force.

Velocity is a measure of the speed of an object and the direction in which it travels.

Velocity is a vector quantity with a magnitude and direction.

Discussion Questions

Before the Game

What is a force? What is a net force? What is the difference between velocity and acceleration? What force is always acting on Earth?

After the Game

At the beginning of the game, you had to push boxes - why did it take more than one knight to push the box? What did the graph show about the relationship between velocity and time, and what do we call a change in velocity over time? If an object is moving at a constant speed, what is its net force? What are examples of friction, gravity, and inertia in the game? How were you able to balance the scale with the treasure chest? Explain how you used Newton's First Law to succeed in the game? Explain how you used Newton's Second Law to succeed in the game?
