Force and Newton's Law Flashcard

Front

What type of force is applied when a student runs and kicks a ball?

Back

Unbalanced force is applied to move the ball.

Front

Between which two points is the car accelerating at a constant velocity?

Back

The car is accelerating at a constant velocity between points AB.

Front

A drag racer accelerated from 0 m/s to 200 m/s in 5 s. What was the acceleration?

Back

The acceleration was 40 m/s².

Front

What is Newton's second law of motion?

Back

Newton's second law states that acceleration (a) is equal to the net force (f) divided by mass (m), or a = f/m.

Front

What type of force resists motion between two surfaces that are pressed together?

Back

Friction is the force that resists motion between two surfaces.

Front

Define balanced forces.

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

Front

What is the formula for calculating force?

Back

Force (f) is calculated using the formula f = m * a, where m is mass and a is acceleration.

Front

What is inertia?

Back

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

Front

What is the relationship between mass and acceleration according to Newton's second law?

Back

According to Newton's second law, as mass increases, acceleration decreases if the force remains constant.

Front

What is the effect of friction on motion?

Back

Friction opposes motion, causing objects to slow down or stop.
