Newton's Law and Forces

Front

What does Newton's second law state about the relationship between force and acceleration?

Back

According to Newton's second law, if you increase the force applied to an object, it accelerates more.

Front

What is the reaction force when a cannon fires a cannonball?

Back

The cannon moving backward is the reaction force.

Front

What is 45 m/s² an example of?

Back

45 m/s² is an example of acceleration.

Front

What does a distance vs. time graph represent?

Back

A distance vs. time graph shows an object's speed.

Front

During which interval is the object speeding up if the graph shows increasing distance over time?

Back

The object is speeding up during the interval A to B.

Front

What is inertia?

Back

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

Front

What is the formula for calculating force?

Back

Force = Mass × Acceleration (F = m × a).

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.

Front

What is an example of Newton's first law of motion?

Back

An example of Newton's first law is a soccer ball remaining at rest until kicked.

Front

What does it mean when forces are balanced?

Back

When forces are balanced, the net force is zero, and the object remains at rest or moves at a constant velocity.
