Force and Translational Dynamics
A net force of 10 N is applied to a 2 kg object. What is the magnitude of the object's acceleration?
2 m/s²
5 m/s²
10 m/s²
20 m/s²
If the mass of an object is doubled while the net force remains constant, what happens to the object's acceleration?
It doubles.
It quadruples.
It halves.
It remains the same.
A 4 kg object experiences a net force of 20 N. What is its acceleration?
2 m/s²
4 m/s²
5 m/s²
80 m/s²
An object with a mass of 2 kg accelerates at 3 m/s². What is the net force acting on the object?
1.5 N
5 N
6 N
12 N
An object is subjected to two forces: 30 N to the right and 10 N to the left. If the object's acceleration is 4 m/s², what is its mass?
2.5 kg
5 kg
7.5 kg
10 kg
An object is subjected to two forces: 50 N to the right and 20 N to the left. If the object's acceleration is 3 m/s², what is its mass?
5 kg
10 kg
15 kg
20 kg
What is the net force on an object moving at a constant velocity of 5 m/s?
5 N
Zero
Depends on the mass
Cannot be determined

A car is moving at a constant velocity. What can you say about the forces acting on the car?
The forces are unbalanced.
The net force is zero.
The car is accelerating.
There are no forces acting on the car.
A box is pushed across a floor at a constant speed. What can you say about the forces acting on the box?
The pushing force is greater than the friction force.
The pushing force is less than the friction force.
The pushing force is equal to the friction force.
There are no forces acting on the box.
A car accelerates from rest. What can you say about the forces acting on the car?
The forces are balanced.
The net force is zero.
The forces are unbalanced.
There are no forces acting on the car.
