Newton's Laws - Science 5

A push or a pull exerted by one object on another, causing a change in motion.

• inertia

• force

• friction

• action

The SPEED and DIRECTION of a moving object.

• acceleration

• gravity

• speed

• velocity

The force one object applies to a second, as in Newton's third law of motion.

• reaction

• action

• balanced forces

• weight

The tendency of a moving object to keep moving in a straight line or of any object to resist a change in motion.

• velocity

• gravity

• speed

• inertia

A change in velocity or position with respect to time.

• deceleration

• gravity

• acceleration

• force

The force with which an object responds to an action, as in Newton's third law of motion.

• reaction

• action

• friction

• weight

A force that opposes the motion of one object moving past another.

• speed

• gravity

• velocity

• friction

Forces that cancel each other out when acting together on a single object.

• gravity

• unbalanced forces

• balanced forces

• weights

A force of attraction, or pull, between any object and any other objects around it.

Hint: You don't find this in space.

• speed

• gravity

• force

• velocity

How fast an object's position changes with time at any given moment.

• inertia

• friction

• velocity
