Forces and interactions

Front

What is a force?

Back

A force is a push or pull that can change the motion of an object.

Front

What is gravity?

Back

Gravity is the force that pulls objects toward each other, such as the Earth pulling us down.

Front

What is an interaction in physics?

Back

An interaction is a situation where two or more objects affect each other's motion.

Front

What happens when two forces act in the same direction?

Back

The forces add together to create a stronger force.

Front

What happens when two forces act in opposite directions?

Back

The forces subtract from each other, resulting in a net force.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is the relationship between mass and gravity?

Back

The more mass an object has, the stronger its gravitational pull.

Front

What is a balanced force?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

Front

What is an unbalanced force?

Back

Unbalanced forces are not equal, causing a change in motion of the object.

Front

What is friction?

Back

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