Front

What does Newton's Second Law state about force?

Back

Force is equal to mass multiplied by acceleration (F = m × a).

Front

How do airbags enhance passenger safety during a collision?

Back

Airbags enhance safety by prolonging the time of impact, which reduces the force experienced by passengers.

Front

Is momentum affected by external forces?

Back

False. Momentum can be affected by external forces.

Front

Is the action-reaction concept part of Newton's Second Law?

Back

False. The action-reaction concept is part of Newton's Third Law.

Front

What two variables influence an object's terminal velocity?

Back

Mass and air resistance influence an object's terminal velocity.

Front

Define momentum in physics.

Back

Momentum is the product of an object's mass and its velocity (p = m × v).

Front

What is the formula for calculating force?

Back

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

Front

What is terminal velocity?

Back

Terminal velocity is the constant speed an object reaches when the force of gravity is balanced by air resistance.

Front

What is the relationship between mass and acceleration according to Newton's Second Law?

Back

The greater the mass of an object, the more force is required to accelerate it.

Front

What happens to an object's momentum if its velocity doubles?

Back

If the velocity doubles, the momentum also doubles, assuming mass remains constant.
