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 motion.

Front

What is the direction of a force?

Back

The direction of a force indicates where the force is applied, such as up, down, left, or right.

Front

Which phase of matter is the least compressible?

Back

Solids are the least compressible phase of matter because their particles are closely packed together.

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. For example, a roller coaster at the top of a hill has high potential energy.

Front

How do you calculate net force when two forces act in opposite directions?

Back

To calculate net force, subtract the smaller force from the larger force and indicate the direction of the larger force.

Front

What happens when forces are balanced?

Back

When forces are balanced, the net force is zero, and the object does not accelerate; it remains at rest or continues moving at a constant speed.

Front

What happens when forces are unbalanced?

Back

When forces are unbalanced, the net force is not zero, causing the object to accelerate in the direction of the greater force.

Front

What is a free-body diagram?

Back

A free-body diagram is a visual representation that shows all the forces acting on an object, helping to analyze the net force.

Front

What is the relationship between mass and weight?

Back

Weight is the force of gravity acting on an object's mass. It can be calculated using the formula: Weight = mass × gravity.

Front

What is the formula for calculating potential energy?

Back

Potential energy (PE) can be calculated using the formula: PE = mass × gravity × height.
