Force and Motion

Front

What are unbalanced forces?

Back

Unbalanced forces are forces that cause an object to accelerate or change its motion. They occur when the net force acting on an object is not zero.

Front

What are balanced forces?

Back

Balanced forces are forces that are equal in size but opposite in direction, resulting in a net force of zero. They do not cause a change in motion.

Front

What is gravity?

Back

Gravity is a force that attracts two bodies towards each other, commonly experienced as the force that pulls objects towards the Earth.

Front

What is net force?

Back

Net force is the overall force acting on an object when all the individual forces are combined. It determines the object's acceleration.

Front

How do you calculate average speed?

Back

Average speed is calculated by dividing the total distance traveled by the total time taken. Formula: Average Speed = Total Distance / Total Time.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object. It occurs when two surfaces come into contact and can cause objects to slow down or stop.

Front

What is acceleration?

Back

Acceleration is the rate at which an object's velocity changes over time. It can be an increase or decrease in speed.

Front

What is the formula for calculating net force?

Back

Net Force = Force applied in one direction - Force applied in the opposite direction.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. An object at rest stays at rest, and an object in motion stays in motion unless acted upon by an external force.
