Physical Science Final Exam Mixed Review

Front

What is displacement in physics?

Back

Displacement is the shortest distance from the initial to the final position of an object, along with the direction.

Front

What is the formula for calculating displacement?

Back

Displacement = Final Position - Initial Position.

Front

What does Newton's first law state?

Back

An object in motion will remain in motion, and an object at rest will remain at rest unless acted upon by an external force.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is net force?

Back

Net force is the total force acting on an object after all the individual forces are combined.

Front

How do you calculate net force?

Back

Net Force = Sum of all forces acting on an object.

Front

What is the unit of force in the International System of Units (SI)?

Back

The unit of force is the Newton (N).

Front

What does a constant speed graph look like?

Back

A constant speed graph is a straight line on a distance-time graph, indicating uniform motion.

Front

What happens to an object if the net force acting on it is zero?

Back

If the net force is zero, the object will either remain at rest or move with a constant velocity.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, acting in the opposite direction of the movement.
