Honors Physics Semester 1 Exam Review

Front

What happens to objects dropped from the same height in a vacuum?

Back

They would hit the ground at the same time.

Front

When does a ball thrown straight upward have a constant acceleration?

Back

During its entire trip.

Front

What does a nonzero net force acting on an object indicate?

Back

The object is definitely being accelerated.

Front

According to Newton’s second law, what happens when the same force is applied to two objects of different masses?

Back

The object with greater mass will experience a smaller acceleration, and the object with less mass will experience a greater acceleration.

Front

In a free-body diagram, what does a force of 5800 N represent when a car is being pulled by a towing cable?

Back

The force exerted by the towing cable on the car.

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) = Net Force (F) / Mass (m).

Front

Define inertia in the context of physics.

Back

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

Front

What is the principle of conservation of energy?

Back

Energy cannot be created or destroyed, only transformed from one form to another.

Front

Explain the difference between speed and velocity.

Back

Speed is a scalar quantity representing how fast an object moves, while velocity is a vector quantity that includes direction.

Front

What is Newton's first law of motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.
