What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion at the same speed and in the same direction unless acted upon by a net external force.

Front

What is inertia?

Back

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

Front

What is force?

Back

A force is a push or pull that can cause an object to accelerate, change direction, or change shape.

Front

What is acceleration?

Back

Acceleration is the rate at which an object's velocity changes over time.

Front

What does it mean for an object to be in motion?

Back

An object is in motion if it changes its position relative to a reference point.

Front

What is the relationship between force and motion?

Back

Force is required to change the motion of an object; without force, an object's motion will remain constant.

Front

What happens to a soccer ball when it is kicked?

Back

The ball accelerates in the direction of the force applied by the kick.

Front

What is the effect of friction on motion?

Back

Friction opposes motion, causing objects to slow down or stop.

Front

How does gravity affect motion?

Back

Gravity pulls objects toward the Earth, affecting their motion and speed.

Front

What is the difference between speed and velocity?

Back

Speed is the distance traveled per unit of time, while velocity includes both speed and direction.
