Force motion and energy Flashcardziz

Front

What happens to the forces acting on a fan when it is turned off?

Back

The forces become balanced, causing the fan to slow down and come to a rest.

Front

How do you calculate the force needed to accelerate an object?

Back

Force (F) is calculated using the formula F = mass (m) × acceleration (a).

Front

What is the formula for calculating force?

Back

F = m × a, where F is force, m is mass, and a is acceleration.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, which can be a change in speed or direction.

Front

What does a distance-time graph indicate when the distance returns to zero?

Back

It indicates that the object has returned to its starting point.

Front

What is the work done when lifting an object?

Back

Work is defined as the force applied to an object multiplied by the distance over which the force is applied.

Front

Is lifting a chair straight up more work than pushing it up a ramp?

Back

No, both actions do the same amount of work if the force and distance are the same.

Front

What is the relationship between force, mass, and acceleration?

Back

According to Newton's second law, the force acting on an object is equal to the mass of the object multiplied by its acceleration.

Front

What is the unit of force in the International System of Units (SI)?

Back

The unit of force is the Newton (N).

Front

What does it mean for forces to be balanced?

Back

Balanced forces mean that the net force acting on an object is zero, resulting in no change in motion.
