Physics Final S1 Review 3

Front

What best describes the relationship between the horizontal and vertical components of a projectile's motion?

Back

Independent

Front

What can you do to loosen a nut with a wrench if it doesn't give?

Back

Extend the lever arm, exert force perpendicular to the lever arm, exert a larger force, or have a friend help you pull on the wrench. All of the above.

Front

What is the net force on an apple weighing 1 N when held at rest in your hand?

Back

0 N

Front

In circular motion, what does the vector of centripetal acceleration represent?

Back

The direction towards the center of the circle.

Front

What is the relationship between the force of a car on a bug and the force of the bug on the car?

Back

The same.

Front

Define projectile motion.

Back

Motion of an object thrown into the air with an initial velocity, affected only by gravity and air resistance.

Front

What is centripetal acceleration?

Back

Acceleration directed towards the center of a circular path.

Front

Explain Newton's Third Law of Motion.

Back

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

Front

What is the formula for calculating force?

Back

Force = mass × acceleration (F = ma).

Front

What is the significance of the net force being zero?

Back

The object is in equilibrium, meaning it is either at rest or moving at a constant velocity.
