FE Physics Review 1

Front

What is displacement?

Back

Displacement is the change in an object's position from its initial position to its final position, measured in a straight line.

Front

How do distance and displacement compare when an object moves in a straight line?

Back

When an object moves in a straight line without changing direction, the distance traveled is equal to the displacement.

Front

What does Newton's 2nd law state?

Back

Newton's 2nd law states that the force acting on an object is equal to the mass of that object multiplied by its acceleration (F = ma).

Front

What is Newton's 1st law of motion?

Back

Newton's 1st law states that an object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity unless acted upon by a net external force.

Front

What is Newton's 3rd law of motion?

Back

Newton's 3rd law states that for every action, there is an equal and opposite reaction.

Front

What type of friction acts on a stationary object?

Back

Static friction acts on a stationary object, preventing it from moving.

Front

What is the difference between static and kinetic friction?

Back

Static friction acts on objects that are not moving, while kinetic friction acts on objects that are sliding past each other.

Front

What is the formula for calculating force?

Back

The formula for calculating force is F = ma, where F is force, m is mass, and a is acceleration.

Front

What is the role of a reference point in motion?

Back

A reference point is a stationary object used to determine the position of another object in motion.

Front

What is the definition of motion?

Back

Motion is the change in position of an object over time.
