Force and Motion

Front

What is force?

Back

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

Front

What is motion?

Back

Motion is the change in position of an object over time.

Front

What is gravity?

Back

Gravity is a force that pulls objects toward each other, such as the Earth pulling objects toward its center.

Front

What is inertia?

Back

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

Front

What happens when two forces act in the same direction?

Back

The forces combine to create a greater force in that direction.

Front

What happens when two forces act in opposite directions?

Back

The forces cancel each other out, resulting in no movement if they are equal.

Front

What is the relationship between mass and gravity?

Back

The larger the mass of an object, the greater the gravitational force it exerts.

Front

What is the effect of applying a greater force on a moving object?

Back

The speed of the object will increase.

Front

What is the effect of applying a force on an object at rest?

Back

The object will start to move.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).
