Forces and Motion Concepts Bell Work

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It occurs when an object speeds up, slows down, or changes direction.

Front

What is net force?

Back

Net force is the total force acting on an object after all the forces are combined. It determines the object's acceleration.

Front

How do you calculate net force?

Back

Net force can be calculated using the formula: Net Force = Mass x Acceleration (F = m*a).

Front

What is gravitational force?

Back

Gravitational force is the attractive force between two masses. It pulls objects toward each other.

Front

What is an applied force?

Back

An applied force is a force that is applied to an object by a person or another object.

Front

What is friction force?

Back

Friction force is the force that opposes the motion of an object. It occurs when two surfaces contact each other.

Front

What is tension force?

Back

Tension force is the force transmitted through a string, rope, or cable when it is pulled tight by forces acting from opposite ends.

Front

What is normal force?

Back

Normal force is the support force exerted upon an object that is in contact with another stable object, acting perpendicular to the surface.

Front

What happens when the net force is zero?

Back

When the net force is zero, the object is either at rest or moving at a constant velocity.

Front

What is the relationship between mass and acceleration?

Back

According to Newton's second law, an object's acceleration is inversely proportional to its mass when the net force is constant.
