5th Grade Force and Motion - Vocabulary

Front

What is an unbalanced force?

Back

An unbalanced force occurs when two or more forces acting on an object are not equal in size or direction, causing the object to change its motion.

Front

What is an inclined plane?

Back

An inclined plane is a flat surface that is tilted at an angle, often referred to as a ramp, which helps to lift or lower objects.

Front

What is gravity?

Back

Gravity is the force of attraction between two masses, such as the Earth and an object, pulling them towards each other.

Front

What is inertia?

Back

Inertia is the natural tendency of an object to remain at rest or to continue moving in a straight line unless acted upon by an external force.

Front

What is a load in physics?

Back

A load is an object that requires a force to be moved over a distance, often used in the context of lifting or carrying.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion, which depends on its mass and speed.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state, such as an object held at a height.

Front

What is friction?

Back

Friction is the force that opposes the motion of an object when it comes into contact with another surface.

Front

What is mass?

Back

Mass is a measure of the amount of matter in an object, usually measured in kilograms or grams.

Front

What is speed?

Back

Speed is the distance traveled by an object in a given amount of time, often measured in meters per second.
