Benchmark 1 Review 24-25

Front

What is net force?

Back

Net force is the overall force acting on an object when all the individual forces are combined. It determines the object's motion.

Front

What does it mean for forces to be balanced?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion of the object.

Front

What is an example of balanced forces?

Back

A book sitting on a high shelf is an example of balanced forces, as the force of gravity pulling it down is balanced by the support force from the shelf.

Front

What is the relationship between metals and metalloids?

Back

Both metals and metalloids can be shiny, but they have different properties such as conductivity and malleability.

Front

What is Newton's First Law of Motion?

Back

An object in motion stays in motion unless acted upon by an unbalanced force.

Front

What is the formula to calculate force?

Back

Force (F) = mass (m) × acceleration (a).

Front

If an object has a mass of 5 kg and an acceleration of 2 m/s², what is the force required to move it?

Back

Force = 5 kg × 2 m/s² = 10 N.

Front

What is the significance of unbalanced forces?

Back

Unbalanced forces cause a change in the motion of an object, such as starting, stopping, or changing direction.

Front

What is an example of an unbalanced force?

Back

A car accelerating when the driver presses the gas pedal is an example of an unbalanced force.

Front

What happens to an object at rest according to Newton's First Law?

Back

An object at rest stays at rest unless acted upon by an unbalanced force.
