Forces

Front

What happens to the acceleration of an object if its mass is halved while the same force is applied?

Back

The acceleration increases by 2.

Front

If all forces acting on an object are balanced, what can be said about its motion?

Back

The object could either move at constant velocity or not move.

Front

How do you calculate the mass of an object if the force acting on it is known?

Back

Use the formula: Mass = Force / Acceleration.

Front

Which object accelerates the most when the same force is applied to different masses?

Back

The object with the least mass accelerates the most.

Front

What is the formula for calculating force?

Back

Force = Mass x Acceleration.

Front

If an object has a mass of 2kg and is moving at +12m/s with an acceleration of -4m/s², what is the unbalanced force?

Back

-8N.

Front

What is the relationship between mass and acceleration when a constant force is applied?

Back

Acceleration is inversely proportional to mass.

Front

Define balanced forces.

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

Front

What is the effect of unbalanced forces on an object?

Back

Unbalanced forces cause an object to accelerate in the direction of the net force.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.
