Physics Final Exam Review

Front

What role does friction play in braking force?

Back

Friction opposes motion and helps stop the vehicle.

Front

How are electric and magnetic fields oriented in an electromagnetic wave?

Back

They oscillate at right angles to each other.

Front

What factors influence gravitational force in space?

Back

Greater mass and smaller distance increase the force.

Front

What determines the position of radiation on the electromagnetic spectrum?

Back

Wavelength and frequency.

Front

What safety feature reduces impact force during a collision?

Back

Airbags reduce impact force by increasing the collision time.

Front

Define friction in the context of motion.

Back

Friction is a force that opposes the relative motion of two surfaces in contact.

Front

What is the relationship between mass and gravitational force?

Back

Gravitational force increases with greater mass.

Front

Explain the concept of electromagnetic waves.

Back

Electromagnetic waves are waves of electric and magnetic fields that propagate through space.

Front

What is the formula for gravitational force?

Back

F = G * (m1 * m2) / r^2, where F is the gravitational force, G is the gravitational constant, m1 and m2 are the masses, and r is the distance between their centers.

Front

How does increasing distance affect gravitational force?

Back

Increasing distance decreases the gravitational force between two objects.
