A push, pull, or hit that can change the motion, shape, or size of an object.

The tendency of an object to resist changes in its state of motion.

The rate of change of velocity.

The force of attraction between any two objects with mass.

A force that opposes motion between two surfaces in contact.

When two or more forces acting on an object cancel each other out, resulting in no change in the object's motion. Think of a tug-of-war where both teams pull with equal strength, causing the rope to stay still.

When forces acting on an object do not cancel each other out, causing the object to change its motion, either by starting to move, stopping, or changing direction.

Newton's first law of motion states that an object at rest will stay at rest, and an object in motion will stay in motion at a constant speed and direction unless acted upon by an unbalanced force. Basically, objects need a push or pull to start moving, stop moving, or change direction.

The amount of matter an object contains. It's a measure of how much stuff is in something.

The relationship between mass and inertia; objects with greater mass have greater inertia. This means it's harder to change their state of motion.

An activity designed to see how objects resist change in motion by sliding a coin out from under a stack of coins.

An activity demonstrating inertia by flicking a card away from under a coin, causing the coin to fall into a glass.

An activity showing inertia by tilting a tray with a water-filled glass; the water spills due to inertia.

A change in velocity. This can be a change in speed or direction.

The mass of an object multiplied by its velocity. It is a vector quantity and its direction is the same as that of the velocity.

The change in momentum of an object. It is equal to the product of the force and the time for which it acts.

The rate of change of momentum of an object is directly proportional to the applied unbalanced force and takes place in the direction of the force.

The product of the constant of proportionality and the product of mass and acceleration.

The constant of proportionality between the force and the product of mass and acceleration. Its value is 1 in the SI system.

The unit of force in the SI system.

Force = mass * acceleration.

For every action, there is an equal and opposite reaction.

The ability to do work.

The energy an object has due to its motion.

The energy an object has due to its position.

The transfer of energy.

A force that opposes the motion of objects. It's a force acting in the opposite direction of the motion.
