physics midterm review

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity in time.

Front

What is the acceleration of a car that travels in a straight line at a constant speed of 100 km/hr?

Back

0 km/hr

Front

How are acceleration and velocity related?

Back

Acceleration is the rate of change of velocity in time.

Front

How does mass affect acceleration?

Back

When mass increases, acceleration decreases, and vice versa (inversely proportional).

Front

What does the law of conservation of momentum state?

Back

The total momentum before a collision is equal to the total momentum after the collision.

Front

How are mass and inertia related?

Back

Mass and inertia are directly proportional; more mass means more inertia.

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 acceleration?

Back

Acceleration (a) = (Final Velocity (v) - Initial Velocity (u)) / Time (t).

Front

What is the unit of acceleration?

Back

The unit of acceleration is meters per second squared (m/s²).

Front

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

Back

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