5th Grade Force and Motion NC

Front

What is gravity?

Back

Gravity is a force that pulls objects toward each other. It is what causes objects to fall to the ground and is responsible for keeping planets in orbit around the sun.

Front

What is friction?

Back

Friction is a force that opposes motion between two surfaces that are in contact. It slows down moving objects and can cause them to stop.

Front

What is motion?

Back

Motion is the change in position of an object over time. It can be described in terms of speed, direction, and distance.

Front

What is speed?

Back

Speed is the distance an object travels in a certain amount of time. It is usually measured in meters per second (m/s) or kilometers per hour (km/h).

Front

What is a force?

Back

A force is a push or pull that can cause an object to move, stop, or change direction. Forces can be contact forces (like friction) or non-contact forces (like gravity).

Front

What is mass?

Back

Mass is the amount of matter in an object. It is usually measured in grams (g) or kilograms (kg) and does not change regardless of location.

Front

What is air pressure?

Back

Air pressure is the force exerted by the weight of air above a surface. It can affect how objects move through the air.

Front

What happens to a ball when it is kicked?

Back

When a ball is kicked, a force is applied to it, causing it to move. The ball will continue to move until forces like friction or gravity slow it down or stop it.

Front

How can speed be measured?

Back

Speed can be measured by calculating the distance traveled by an object in a certain amount of time. For example, if a car travels 100 meters in 5 seconds, its speed is 20 m/s.

Front

What is a graph of motion?

Back

A graph of motion shows how an object's position changes over time. It can represent speed, direction, and whether the object is speeding up or slowing down.
