STAAR Physics Review

Front

What is Speed?

Back

The distance an object travels in a specific amount of time.

Front

What is an Unbalanced Force?

Back

A force that causes an object to accelerate, change direction, or change shape.

Front

Calculate the speed: Reese can run 10 meters in 5 seconds.

Back

2 meters/sec

Front

What is Net Force?

Back

The overall force acting on an object, calculated by combining all individual forces. If forces are balanced, the net force is 0.

Front

What is Kinetic Energy?

Back

The energy of motion, which depends on the mass and speed of an object.

Front

What is Velocity?

Back

The speed of an object in a specific direction.

Front

What is Acceleration?

Back

The rate at which an object changes its velocity.

Front

What is Potential Energy?

Back

The stored energy of an object due to its position or state.

Front

What is Gravity?

Back

A force that attracts two bodies towards each other, commonly experienced as the force that pulls objects towards the Earth.

Front

What is a Balanced Force?

Back

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