Dynamics C

Front

What happens to an object's acceleration as the net force on it increases?

Back

The object's acceleration will increase.

Front

What is the formula to calculate net force?

Back

Net Force = Mass x Acceleration (F = m*a)

Front

If an object has a mass of 82 kg and experiences a gravitational force of 9.8 m/s², what is the weight of the object?

Back

Weight = Mass x Gravity = 82 kg x 9.8 m/s² = 803.6 N.

Front

What is the effect of increasing mass on acceleration when the net force is constant?

Back

As the mass of the object increases, its acceleration will decrease.

Front

What is air resistance?

Back

Air resistance is a force that opposes the motion of an object through the air.

Front

How do you calculate acceleration when net force and mass are known?

Back

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

Front

What is the acceleration due to gravity near the Earth's surface?

Back

The acceleration due to gravity near the Earth's surface is approximately 9.8 m/s².

Front

If an object is falling and encounters a resistance force, how does it affect its acceleration?

Back

The acceleration of the object will decrease due to the opposing resistance force.

Front

What is the net force acting on an object if it has a weight of 803.6 N and encounters a resistance of 20 N?

Back

Net Force = Weight - Resistance = 803.6 N - 20 N = 783.6 N.

Front

Define net force.

Back

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