Physics Final Exam Review

Front

What is the work done by gravity when lifting an object?

Back

The force of gravity does negative work when the worker lifts the bucket.

Front

What is the tendency of an object to maintain its state of motion?

Back

Inertia.

Front

What causes a moving object to change direction?

Back

Force.

Front

What does a change in gravitational force affect?

Back

Weight.

Front

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

Back

The acceleration of an object is directly proportional to the net external force acting on the object and inversely proportional to the mass of the object.

Front

Define work in physics.

Back

Work is done when a force causes an object to move in the direction of the force.

Front

What is the formula for calculating work?

Back

Work = Force x Distance x cos(θ), where θ is the angle between the force and the direction of motion.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.

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.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object.
