Force and Motion vocabulary #11

Front

What is the scientific term for when an object stays at rest?

Back

Inertia: The tendency of an object to remain at rest or in uniform motion unless acted upon by an external force.

Front

What is the force that slows down or stops an object in motion?

Back

Friction: A force that opposes the motion of an object, causing it to slow down or stop.

Front

What unit is used to measure force, named after Sir Isaac Newton?

Back

Newtons: The unit of force in the International System of Units (SI), symbolized as 'N'.

Front

What is the force that pulls objects toward the center of the Earth?

What is the force that can change the motion of an object?

Back

Force: A push or pull that can cause an object to accelerate, change direction, or change shape.

Front

What is the force that acts between two surfaces in contact?

Back

Friction: The force that opposes the relative motion of two surfaces in contact.

Front

What is the effect of gravity on objects in free fall?

Back

Objects in free fall accelerate downward due to gravity, at a rate of approximately 9.8 m/s².

Front

What is the relationship between mass and weight?

Back

Weight: The force of gravity acting on an object's mass, calculated as weight = mass × gravity.
