8th Grade Science - Force and Acceleration

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, acting in the opposite direction to the movement.

Front

What does Newton's second law of motion 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 (F = m x a).

Front

What two factors does acceleration depend on?

Back

Acceleration depends on net force and mass.

Front

How do you find the net force when two forces act in the same direction?

Back

You find the net force by adding the two forces together.

Front

What is the difference between acceleration and velocity?

Back

Acceleration is the change in velocity over time, while velocity is the distance covered over time.

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) = Net Force (F) / Mass (m).

Front

What is net force?

Back

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

Front

What happens to acceleration if mass increases while the net force remains constant?

Back

If mass increases and net force remains constant, acceleration decreases.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What is the relationship between mass and acceleration according to Newton's second law?

Back

According to Newton's second law, as mass increases, acceleration decreases if the net force is constant.
