Force and motion

Front

What does Newton's third law state?

Back

For every action, there is an equal and opposite reaction.

Front

How does a speed boat respond when it hits a large wave while traveling at a constant rate?

Back

It would go backward a bit.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity.

Front

Which has more momentum: a car stopped at a red light or a bike moving at 15 mph?

Back

The bike has more momentum.

Front

What is the formula for calculating momentum?

Back

Momentum (p) = mass (m) × velocity (v).

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object.

Front

What is the unit of force in the International System of Units (SI)?

Back

The unit of force is the Newton (N).

Front

What is the relationship between force, mass, and acceleration?

Back

According to Newton's second law, Force (F) = mass (m) × acceleration (a).

Front

What is inertia?

Back

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