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

Front

What are balanced forces?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

Front

What are unbalanced forces?

Back

Unbalanced forces are not equal and can cause an object to accelerate or change direction.

Front

What is gravity?

Back

Gravity is a force that pulls objects toward each other, such as the Earth pulling objects toward its center.

Front

What is speed?

Back

Speed is the distance an object travels per unit of time.

Front

What is acceleration?

Back

Acceleration is the rate at which an object changes its velocity.

Front

What is a speed vs time graph?

Back

A speed vs time graph shows how speed changes over time, with time on the x-axis and speed on the y-axis.

Front

What does a straight line on a speed vs time graph indicate?

Back

A straight line indicates constant speed.
