Forces and Motion

Performance Expectation

MS-PS2-2: Plan an investigation to provide evidence that the change in an object's motion depends on the sum of the forces on the object and the mass of the object.

In Student-Friendly Words...

I can investigate how forces and an object's mass affect its motion.

Big Ideas

A larger force causes a greater change in motion.
More massive objects require more force to change their motion.
Balanced forces do not change an object's motion.
Unbalanced forces cause objects to speed up, slow down, or change direction.

Real-World Connections

Sports

Whether you're kicking a soccer ball, shooting a basketball, or swinging a bat, the force you apply changes the object's motion.

Driving

Cars need different amounts of force to accelerate, stop, or turn depending on their mass and motion.

Riding a Bike

You constantly use forces to start, stop, speed up, slow down, and change direction while riding.

Engineering & Design

Engineers use forces and motion when designing everything from roller coasters to bridges to vehicles.
