Newtons Laws of Motion

Front

What is Newton's First Law of Motion?

Back

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

Front

What is the unit of measurement for speed?

Back

Meters per second (m/s)

What happens to an object's motion when the forces acting on it are balanced?

Back

The object's motion remains unchanged.

What is acceleration?

Back

Acceleration is the change in speed per unit of time.

Front

What force opposes the motion of an object?

Back

Friction opposes the motion of an object.

Front

What is Newton's Second Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).

Front

What is the definition of force?

Back

A force is a push or pull on an object resulting from the object's interaction with another object.

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 weight?

Back

Weight is the force exerted by gravity on an object, calculated as weight = mass × gravity (W=mg).

Front

What is the effect of unbalanced forces on an object?

Back

Unbalanced forces cause an object to accelerate in the direction of the net force.
