Force and Motion (Based on Amplify Science) Chapters 1-4

A stronger force can cause a greater change in velocity.

Velocity is the speed of something in a given direction.

The lighter object will have a greater change in velocity.

The two objects move in the opposite direction with the same strength.

Force is strength or energy as an attribute of physical action or movement.

As mass increases, acceleration decreases when a constant force is applied.

Newton's second law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Friction opposes the motion of objects, causing them to slow down or stop.

Force is calculated using the formula F = m * a, where F is force, m is mass, and a is acceleration.

Inertia is the tendency of an object to resist changes in its state of motion.
