Push and Pull Forces Flashcards

Grade 2 · Science · Flashcards

Review key vocabulary about forces, motion, gravity, and friction.

Flashcards

Force: A push or pull that makes an object move, stop, or change direction
Push: A force that moves an object away — kicking a ball, pushing a door closed
Pull: A force that moves an object closer — opening a drawer, pulling a rope
Gravity: A force that pulls all objects toward Earth's center; causes things to fall
Friction: A force between surfaces that slows moving objects down
Motion: A change in position; an object in motion is moving
Speed: How fast an object is moving; a bigger force creates more speed
Direction: The path an object is moving; forces can change an object's direction
Weight: The force of gravity pulling on an object's mass
Smooth surface: A surface with low friction — like ice or glass — objects slide easily
Rough surface: A surface with high friction — like gravel — objects slow down quickly
Newton: The unit used to measure force, named after scientist Isaac Newton
