Semester 1 Physical Science Final

Front

What is net force?

Back

Net force is the overall force acting on an object when all the individual forces are combined. It determines the object's acceleration.

Front

If a person exerts a force of 45 N to the left and another exerts 32 N to the right, what is the net force?

Back

13 N Left

Front

What type of graph is used to compare different groups?

Back

Bar graph

Front

What type of graph is used to show changes over time?

Back

Line graph

Front

What is displacement?

Back

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

Front

If a man walks 5 miles forward, 6 miles backward, and then 2 miles forward, what is his displacement?

Back

1 mile forward

Front

What does Newton's second law state?

Back

Newton's second law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

What is inertia?

Back

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

Front

What is the formula for calculating force?

Back

Force = mass × acceleration (F = ma)

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.
