Forces and Motion Concepts

Front

What is a force?

Back

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

Front

What is motion?

Back

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

Front

What is gravity?

Back

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

Front

What happens when forces are balanced?

Back

When forces are balanced, there is no change in motion; the object remains at rest or continues moving at a constant speed.

Front

What happens when forces are unbalanced?

Back

When forces are unbalanced, the object will accelerate, decelerate, or change direction.

Front

What is air resistance?

Back

Air resistance is a force that opposes the motion of an object through the air, often slowing it down.

Front

How does mass affect motion?

Back

An object with more mass requires more force to change its motion compared to an object with less mass.

Front

What is acceleration?

Back

Acceleration is the rate at which an object changes its velocity, which can be an increase or decrease in speed.

Front

What is the relationship between mass and weight?

Back

Weight is the force of gravity acting on an object's mass; weight = mass x gravity.

Front

What is inertia?

Back

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