Understanding Force and Motion

What is the formula to calculate force?

• force = mass / acceleration

• force = mass x acceleration

• force = mass + acceleration

• force = mass - acceleration

If an object has a mass of 5 kg and an acceleration of 2 m/s^2, what is the force acting on it?

• The force acting on the object is 7 N.

• The force acting on the object is 10 N.

• The force acting on the object is 15 N.

• The force acting on the object is 3 N.

What is the acceleration due to gravity on Earth?

• 7.93 m/s^2

• 5.67 m/s^2

• 9.81 m/s^2

• 10.25 m/s^2

If two forces of 10 N and 5 N are acting in the same direction, what is the net force?

• 25 N

• 0 N

• 15 N

• 2 N

How does an increase in mass affect the acceleration of an object under a constant force?

• The acceleration of the object becomes negative.

• The acceleration of the object decreases.

• The acceleration of the object remains the same.

• The acceleration of the object increases.

How does an increase in force affect the acceleration of an object with constant mass?

• The acceleration of the object will increase

• The acceleration of the object will decrease

• The acceleration of the object will become negative

• The acceleration of the object will remain constant

If an object has a mass of 10 kg and an acceleration of 3 m/s^2, what is the force acting on it?

• The force acting on the object is 20 N.

• The force acting on the object is 30 N.

• The force acting on the object is 40 N.

• The force acting on the object is 50 N.

If two forces of 20 N and 10 N are acting in the opposite direction, what is the net force?

• 30 N

• 10 N

• 0 N

• 20 N

How does a decrease in force affect the acceleration of an object with constant mass?

• The acceleration of the object will increase

• The acceleration of the object will decrease

• The acceleration of the object will become negative

• The acceleration of the object will remain constant

If three forces of 15 N, 10 N and 5 N are acting in the same direction, what is the net force?

• 30 N

• 20 N

• 0 N

• 40 N
