5th grade Force

Front

What is force?

Back

A push or pull on an object that can cause it to move, stop, or change direction.

Front

What is inertia?

Back

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

Front

How does mass affect force?

Back

The greater the mass of an object, the greater the force needed to accelerate it.

Front

What happens to an object in motion when a force is applied?

Back

The object will change its motion, either speeding up, slowing down, or changing direction.

Front

What is acceleration?

Back

The rate at which an object changes its velocity.

Front

What is friction?

Back

A force that opposes the motion of an object, caused by the contact between surfaces.

Front

What is the relationship between force and acceleration?

Back

Force equals mass times acceleration (F = ma).

Front

What is momentum?

Back

The quantity of motion an object has, calculated as mass times velocity.

Front

What is the effect of gravity on objects?

Back

Gravity pulls objects toward the center of the Earth, affecting their motion.

Front

What is a balanced force?

Back

Forces that are equal in size but opposite in direction, resulting in no change in motion.
