An object won’t move if you don’t push it. A moving object will continue moving if nothing pushes or pulls it. If not acted on by external force. An object will move if you push it. Lighter objects need a smaller push to move them compared to heavier objects.

An object won’t move if you don’t push it. • A moving object will continue moving if nothing pushes or pulls it. If not acted on by external force. • An object will move if you push it. • Lighter objects need a smaller push to move them compared to heavier objects. • If you push an object, it will push back.
Gravity is a force that pulls objects toward the Earth. • Friction is a force in the opposite direction that prevents motion. Moves slowly with Friction Moves faster without Friction
An object won’t move if you don’t push it. • A moving object will continue moving if nothing pushes or pulls it. The wall stopped the block, but the stick figure kept moving because nothing stopped it.
Balanced Forces = pushes or pulls that are the same strength, but in opposite directions. This results in no movement of the object. • Unbalanced Forces = pushes or pulls that cause an object to move. Can change how fast an object is moving (speed) and which way an object is moving (direction).
Lighter objects need a smaller push to move them compared to heavier objects
If you push an object, it will push back. • Forces come in pairs. • The force on the first object is the same as the force on the second object. • The direction of the force on the first object is opposite to the direction of the force on the second object. The rocket (1st object) pushes the gases (2nd object)down out of the engine and the gases (2nd object) push back up on the rocket (1st object).
