Physics Semester Review

Front

What is the sum of all forces acting on an object?

Back

Net Force

Front

What is the net force acting upon an object if Fnet = 0 N?

Back

The object is in equilibrium, meaning all forces are balanced.

Front

If Jerry walked from home to school and then to the park, what is his total displacement if he walked 2 km to school and 5 km to the park?

Back

2 km (displacement is the shortest distance from the starting point to the endpoint).

Front

What will cause an object to move?

Back

Unbalanced forces.

Front

What does Newton's third law state?

Back

For every action, there is an equal and opposite reaction.

Front

Define contact force.

Back

A force that acts at the point of contact between two objects.

Front

What is balanced force?

Back

Forces that are equal in size and opposite in direction, resulting in no change in motion.

Front

What is unbalanced force?

Back

Forces that are not equal and opposite, causing a change in motion.

Front

What is displacement?

Back

The shortest distance from the initial position to the final position, including direction.

Front

What is the formula for calculating net force?

Back

Fnet = F1 + F2 + ... + Fn (sum of all forces acting on an object).
